Knowify vs Foundation Software: Which Fits in 2027

The short answer for trade contractors and builders

For a specialty trade contractor that already keeps its books in QuickBooks Online, the category decision is bidding and job-cost software that syncs with that ledger, and Knowify is the one to test first. For a firm that wants a construction-specific accounting system to replace its general ledger, the category is construction accounting software, and Foundation Software is the one to price out. Construction accounting software tracks cost, billing and payroll by job, so an owner can see whether each project is making money before it closes.

Neither product has been renamed, merged or discontinued in the sources reviewed, so this search compares two current products. Foundation's ownership is the larger open question, covered in its own section below.

TL;DR: Pick Knowify if you bid and bill as a trade contractor, need job costing at a published price, and want QuickBooks to stay your books. Pick Foundation Software if you need a construction-specific general ledger, WIP reporting and certified payroll, and you will accept a quote before you see a price.

Key Takeaways

• Knowify publishes its plan prices; Foundation Software publishes none and routes buyers to a quote.

• Job costing and real-time WIP reporting sit on Knowify's Advanced tier, not on Core.

• Knowify syncs bills, invoices, payments and retainage with QuickBooks Online; Foundation presents itself as a replacement for QuickBooks rather than a companion.

• Foundation's most detailed documented features are job costing, change-order tracking and WIP reports, while its estimating tools are delivered through partners.

• Thoma Bravo has owned Foundation since its acquisition, and a reported sale is unconfirmed.

• Automation can draft bill codes and raise alerts around either system, but a named person should approve bill coding, change orders and billing.

Who owns each product and what has changed

Foundation Software, LLC is owned by the private equity firm Thoma Bravo. Thoma Bravo announced on August 31, 2020, that it had completed its acquisition of Foundation Software, according to Thoma Bravo (2020).

A September 3, 2026 report relayed by Pipeline Road says Thoma Bravo is exploring a sale of the company. Reported sale value: more than $2bn, unconfirmed according to Pipeline Road (2026).

The report cites people familiar with the matter and does not say a deal has been agreed. For a buyer, a change of owner could alter pricing, support or the product roadmap, so ask any vendor for renewal pricing and data-export terms in writing before you sign.

I found no acquisition reports for Knowify. The main ownership-related news I found is a sales and referral agreement with Intuit, the QuickBooks maker, under which the two companies jointly introduce contractors to a combined offering, as described in Intuit's announcement. That agreement points to deeper QuickBooks Online integration, not to a change in control.

How we evaluated these tools

This comparison weights six criteria by what a small contractor actually decides on: whether job costs are tracked, whether the books stay clean, whether an estimate carries into the job, whether hours and changes reach the ledger, whether a price is visible before a sales call, and how much an ownership change could matter. The weights sum to 100%. They are our judgment for a buyer, not a vendor or industry standard.

Capterra, G2 and Software Advice returned access errors when we tried to open their pages, so this article does not cite ratings from those sites directly. The one rating figure used comes from a third-party guide that we could open.

Feature matrix: what each product covers

The table holds vendor-published facts. Our reading follows it.

Our read: the two products have different centers of gravity. Knowify is built around the bid-to-bill loop for trades, with QuickBooks as the ledger. Foundation is built around a construction general ledger with WIP and payroll rules, and it asks buyers to replace QuickBooks rather than sit beside it.

Pricing and total cost of ownership

Knowify is the only one of the two that prints plan prices, and its pricing page places two prices beside each plan under a Yearly/Monthly toggle without labeling which is which. Advanced: $329 or $399 per month for 10 users according to Knowify (2026). The same page lists Core at $99 or $149 per month for one user, with each added user at $29 per month, according to Knowify (2026). Enterprise carries no price on the page and points buyers to a sales conversation.

Pricing checked October 29, 2026. Foundation Software's pricing page publishes no dollar amounts and says its pricing is customized to what the business requires, according to Foundation Software.

The table uses only the figures cited above. Annual cost is the monthly price times 12, before any discount, tax or implementation cost. A third-party guide reads the lower Knowify price as the annual rate and the higher one as month-to-month, and places Knowify at a $1M to $10M revenue range and Foundation at $3M to $15M, according to Dupple (2026). Some third-party guides quote estimates for Foundation's pricing, but Foundation's own learn article publishes no figures, so this article uses none. A Foundation total cannot be entered in the table; any figure would need that vendor's written quote for the modules you need.

Knowify: where it fits and where it does not

Knowify is built for trade and subcontract work. Its website says it "was built from the ground up with specialty contractors in mind" and that it was built "to complement QuickBooks." The product spans estimating, change orders, scheduling, daily logs, a client portal, time tracking and job costing, but those features are split across tiers.

Best fit: specialty and trade firms that bill through QuickBooks Online and want estimates, change orders and job cost in one tool. Its QuickBooks page lists what moves each way: clients, vendors, bills, invoices, payments, deposits, retainage and time entries go to QuickBooks, while accounts, classes and tax codes come back.

Limitations: Core has no job costing. QuickBooks Desktop and Intuit Enterprise Suite sync only on the Enterprise tier. Core estimates are fixed-price only, and cost-plus, time-and-materials and subcontract templates come with Advanced. Vendor bills are created in Knowify rather than QuickBooks, so payments can be recorded on either side.

Implementation: the vendor describes setup as a few clicks inside Knowify, but nothing sends until default income and expense accounts are set for each client and vendor. Project sync requires QuickBooks Online Plus and Advanced, so check your QuickBooks edition before you buy.

Our read: Knowify is the lower-friction first test for a subcontractor. The main risk is the tier. If job costing is the reason you are buying, Core is not the plan to compare.

Foundation Software: where it fits and where it does not

Foundation describes itself as construction accounting software built for contractors. Its module list runs through general ledger, accounts payable and receivable, purchase orders and subcontracts, payroll, inventory and fixed assets.

Its job costing page describes budgets built on a company's own cost structure, split by custom cost codes or standard CSI divisions, with WIP and over/under billing reports, according to Foundation Software. Change orders are tracked by status, and the budget updates on approval.

Foundation on Capterra: 4.3 from 388 reviews according to ToolRadar (2026). The same guide lists lower ratings on G2, and we could not open Capterra or G2 ourselves to check it.

Best fit: firms that want a construction-specific ledger with WIP, job costing and certified payroll, and that expect to replace QuickBooks.

Limitations: the vendor's QuickBooks page presents FOUNDATION as an upgrade from QuickBooks and describes no sync, so plan a migration rather than a parallel setup. The estimating tools it lists appear as partners without a described integration. The same third-party guide lists dated interface design and pricing aimed at established contractors as weaknesses.

Implementation: pricing is quote-based, and the vendor's own page asks buyers to fill out a form and then see a personalized demo, so plan for a sales process before any number arrives.

Our read: Foundation's quote-only pricing and the reported sale make it a poor fit if you need a number this week. It is the system to evaluate if your job is a construction ledger rather than a faster bid-to-bill loop.

A worked example with illustrative numbers

Take an illustrative electrical subcontractor with 11 people logging into the system, 18 open jobs and 60 vendor bills a month; these are assumptions for the arithmetic, not customer data. The Advanced tier covers 10 users at $329 per month on the annual reading and $399 month-to-month. Adding the eleventh user at the $29 per-user price cited above, which the pricing page also lists for Advanced, brings the total to $358 per month, or $4,296 a year ($358 × 12). At $399 month-to-month plus $29, the same 11 users cost $428 a month, or $5,136 a year, which is $840 more. If a bookkeeper spends 2 minutes coding each of the 60 bills to a job and cost code, that is 120 minutes, or 2 hours a month, before anyone reviews the codes. A workflow can shorten the matching step, but it cannot approve the code.

Where automation fits around either system

US Tech Automations can configure a proposed bill-coding workflow for either system. Its trigger is a new vendor bill or an emailed vendor invoice arriving in the accounting system, or a bill created in the job tool. Its action reads the vendor, amount and job reference, matches them against open jobs and an approved cost-code list, and drafts a code. Its output is a coded draft in a review queue, with unmatched vendors routed to a person instead of guessed. Prerequisites are read access to bills through the accounting system's API or a scheduled export, an approved cost-code list, and one named approver. Review points: a bookkeeper approves each draft before it posts, and any bill above a threshold the owner sets goes to the owner.

US Tech Automations would configure a second, proposed workflow for change orders. Its trigger is a change order moving to approved in the job system. Its action compares the approved amount with the remaining budget on the affected cost code and drafts a summary for the project manager. Its output is an alert and summary, not an automatic change to an invoice. Prerequisites are API or export access to change-order records. Knowify lists change orders as a native module, while the Foundation pages we opened describe no public API, so confirm export access in writing before designing the trigger. Review point: the owner signs off before any billing change is made.

The do-it-yourself alternative is stitching these steps together in Zapier, Make or n8n. Those tools can keep run histories, retries and error branches when configured, and they can produce audit evidence. The builder still has to design and own observability, idempotency so a retried trigger does not post the same bill twice, escalation, access controls, and maintenance whenever either accounting system changes. A proposed US Tech Automations design would configure those same pieces for each workflow, with the prerequisites and review points above still in force.

Who this is for and who should look elsewhere

Firm size is a useful lens. NCCER's 2026 fact sheet, drawing on Census County Business Patterns data for 2023, says establishments with 10 to 249 employees employ the largest share of the construction workforce, according to NCCER (2026). If you sit in that band, count users and reporting needs before you choose a tier, because Knowify's plans are priced by user count and Foundation's quote depends on what the business requires.

Knowify fits a subcontractor or specialty trade that bills through QuickBooks Online and wants bids, change orders and job cost in one tool, with a published price to compare.

Red flags: you need job costing on the first plan you buy; your books run on QuickBooks Desktop, which only the Enterprise tier syncs; you need a general contractor's full construction ledger.

Foundation Software fits a firm that wants a construction-specific general ledger with WIP, job costing and certified payroll, expects to replace QuickBooks, and can run a quote-based buying process.

Red flags: you need a price before a sales call; you want QuickBooks to remain the ledger; you need a modern interface, since a third-party guide lists dated design as a weakness.

When NOT to use US Tech Automations: a firm with a few bills a week and one bookkeeper does better with the vendor's native sync and a written approval checklist, since a workflow adds access, testing and maintenance that low volume does not repay. A firm that only needs basic job reports on QuickBooks should stay with QuickBooks, because the native job features already answer that question. A firm that has not yet picked an accounting system should choose one first, because a workflow built on a system you may leave is wasted effort.

Decision checklist

• Do you bid and bill as a trade contractor? If yes, start with Knowify.

• Do your books live in QuickBooks Desktop? If yes, Knowify's Desktop sync sits on the Enterprise tier only.

• Do you need job costing from the first plan? If yes, Core is not enough.

• Do you need WIP across many jobs, certified payroll and a general ledger? If yes, request a Foundation quote.

• Do you need a price before a sales call? If yes, Knowify is the one to evaluate first.

• Have you asked for renewal and data-export terms in writing? Do that before either purchase.

Common questions before you choose

Does Knowify replace QuickBooks?

No. Knowify is built to sit beside QuickBooks Online, which stays the ledger, and the vendor says it was built "to complement QuickBooks."

Does Foundation Software publish prices?

No. Its pricing page says pricing is customized to what the business requires and routes buyers to a form and a representative.

Who owns Foundation Software?

Thoma Bravo has owned it since its acquisition was completed, and a reported sale is unconfirmed, as covered in the ownership section above.

Which one costs less for a 10-user crew?

You cannot tell from public information, because Foundation publishes no price. On Knowify, the Advanced tier includes 10 users and job costing, and that is the plan to compare against any Foundation quote.

Can I start on Core and add job costing later?

Not on the same tier. Core does not include job costing, so you would need to move to Advanced or Enterprise before job costing is available.

Conclusion

Start with the decision you actually face. A trade contractor who bids, bills and keeps QuickBooks as the ledger should test Knowify first, with the Advanced tier as the comparison point because it carries job costing. A firm that needs a construction ledger with WIP, job costing and certified payroll should request a Foundation quote, after asking about the reported sale and renewal terms. If you then want a workflow layer on top of either, see how US Tech Automations configures this, with the review points kept in place.
