Car Sales Invoice Software 2027: 4 Steps to Choose

Short answer: pick the system that already holds the deal

Car sales invoice software is any tool that produces the invoice and sale record for a vehicle deal from its price, fees, tax, and buyer data. In our view, the first decision is whether the deal is already closed in a dealer management system (DMS). If it is, choose the DMS whose invoice and accounting output you can verify, and use a general invoicing tool only for invoices the DMS does not cover. If it is not, a general tool can issue invoices, but someone will retype the deal details by hand. The market is large: Franchised light-vehicle dealers: 16,990 in 2025 according to NADA Data (2025). That count covers franchised dealers only, so it sizes the franchised segment rather than every independent lot.

TL;DR: keep the invoice in the system that holds the deal, prove the accounting export with one closed deal, and budget from published prices rather than from listicles.

Key Takeaways

• Decide first whether deals close in a DMS, because that answer removes most of the field.

• Four of the seven vendors on our list publish a price on their own pages; three are quote-based on the pages we opened.

• None of the dealer-system pages we opened describe invoice output in enough detail to confirm it, so request a sample invoice from a closed deal.

• Plan records around the IRS default of 3 years, with longer periods for the listed exceptions.

• Automation helps only after the DMS export and the chart of accounts are correct, and a person approves each draft.

Who this is for

This guide is for an owner or operations lead at a small dealership who is close to choosing and wants a direct answer. It fits an operation that already closes deals in some system and needs the invoice, the deal file, and the bookkeeping to agree. It does not fit a multi-rooftop group that needs enterprise reporting, which this comparison does not cover in depth; for reporting specifics, see our reporting software guide.

Red flags: nobody owns the accounting mapping, the deal file lives only on paper, or the only shortlisted vendor requires a quote before any price can be compared.

How we evaluated these tools

The weights below are our analysis, not vendor data. We read each vendor's own pages against them and did not assign numeric scores to vendors, because the public pages do not support a fair numeric ranking. This is a desk review of public pages checked October 18, 2026; no product was used or trialed for this article.

Two rules followed from these weights. Invoice output carries the most weight because an invoice that does not match the deal is the costliest error. We also did not fill a missing price with a third-party figure. Where we use an independent review site, we label it as a cross-check rather than a list price.

What each vendor page documents

The matrix records what each page we opened says. A "Not described" cell means the page does not say, which is not the same as saying the feature is missing, so ask each vendor in writing.

What the prices say and what they leave out

Pricing checked October 18, 2026.

Prices appear only where the vendor's own pricing page showed them. The Simple Start plan on QuickBooks Online is listed as Simple Start plan on QuickBooks Online: $19 per month for three months according to Intuit QuickBooks (2026). The page shows $38 as the rate after that promotion, with one user and no listed invoice limit. Its Free plan allows 2 invoices per month, which is too few for deal volume.

The AutoManager figure is Dealer management system starts at $88 per month according to AutoManager (2026). The page lists no user limits or annual pricing, and it lists website and CRM plans as separate lines.

For DealerCenter, DMS plan on DealerCenter: $99 per month according to DealerCenter (2026). The Integrated Accounting plan on DealerCenter is also $99 per month, and eContract costs $3.00 per contract, with deal printing at $5 per contract.

The pages we opened for DMS Complete, Tekion, and CDK Global list no plan prices, so those rows read Quote-based. Illustrative scenario, not a customer: a dealership that invoices 30 sold deals a month sends 360 invoices a year (30 × 12), which leaves 140 invoices under the 500-invoice annual cap on Zoho Invoice's free plan (500 − 360 = 140). That plan covers only two users, so a third person needs a plan the page does not price. On the free plan on QuickBooks Online, 30 invoices a month exceeds the two-invoice monthly limit by 28 (30 − 2 = 28). On the Simple Start plan, the same 30 invoices carry no listed limit, and the 12-month cost comes to $399: $19 for three promotional months ($57) plus $38 for nine months ($342). In Zoho's invoice records, due_date sets when an invoice falls due, so a reminder check can read the overdue status before anyone calls the buyer.

The table below restates the same 30-deals-a-month scenario against each published limit.

Who should choose each vendor

Vendor profiles: best fit, limits, and evidence

QuickBooks Online

Best fit: a dealership that already keeps its books in QuickBooks and needs invoices for sales outside the DMS, such as dealer-to-dealer transactions. Limitations: the pages we opened describe general invoicing, not dealer deal fields, and the Free plan's invoice cap is low for deal volume. Implementation: pair it with a DMS export, and have the bookkeeper map sale, tax, and fee lines to accounts before the first live invoice. Evidence: Intuit QuickBooks pricing.

Zoho Invoice

Best fit: a small operation that needs a no-cost invoicing tool for a limited number of invoices and two users. Limitations: the Free plan on Zoho Invoice: 500 invoices per year according to Zoho Invoice (2026), at $0 with up to two users, and the page does not describe dealer deal fields. Implementation: Zoho's Invoices API reference lists invoice_number, customer_id, and due_date as invoice fields, so any DMS export has to map to those names. Evidence: Zoho Invoices API reference.

DealerCenter

Best fit: a dealership that wants a dealer-specific DMS with a separately priced accounting plan, and that will close and paper deals in the same system. Limitations: the pricing page does not say whether invoices are created in the DMS, and the QuickBooks integration appears in site navigation without a price, so ask whether it is included. Implementation: the Integrated Accounting plan lists automated posting of journal entries to the general ledger, so chart-of-accounts mapping is the main setup task. Our read: per-contract fees mean cost rises with every deal, so model them against your monthly volume. Evidence: DealerCenter pricing.

AutoManager

Best fit: a used-car dealership that wants a dealer management system with a published starting price and a listed QuickBooks partnership. Limitations: the pricing page shows no user limits, seat counts, or annual pricing, and the home page does not describe how invoices are created. SelectHub lists AutoManager at $88 per month, according to SelectHub, and it describes that figure as its own analysis rather than a list price. Implementation: the QuickBooks partner logo signals a connection, but it does not show the data mapping, so test one closed deal end to end. Evidence: AutoManager pricing.

DMS Complete

Best fit: a dealer that wants a cloud DMS with sales desk and F&I modules and is willing to request a demo before pricing. Limitations: the pricing page lists no plan prices and routes buyers to a request-demo form or phone contact, and invoicing is not described on the pages we opened. Implementation: before comparing, ask for a written price, a sample invoice, and an accounting export file. Evidence: DMS Complete pricing page, which lists no plan prices.

Tekion

Best fit: a dealer that wants one cloud platform spanning DMS, CRM, digital retail, and payments, and accepts a sales-led process. Limitations: no published pricing, and the site names an Accounting AI agent without describing invoice or ledger features. Implementation: ask for the accounting export format and whether Accounting AI posts to the general ledger. For a direct enterprise comparison, see our Tekion vs CDK comparison. The only Tekion page we opened is its home page, so we link none here.

CDK Global

Best fit: a larger dealer that needs a full DMS with front office, fixed operations, and dealer-wide data, and can run an enterprise sales cycle. Limitations: no published pricing, and the site we opened does not describe invoicing or accounting features. Implementation: get the migration scope in writing before any contract discussion, since data movement is the largest setup task. The only CDK page we opened is its home page, so we link none here.

When NOT to use US Tech Automations: skip a custom workflow if a free or fixed-price tool already covers your invoices, such as a dealership that issues only a handful of invoices a month. If your DMS export already maps cleanly to your ledger and your bookkeeper approves every entry, a workflow adds a review step you may not need. If nobody will own the exception log, access controls, and draft approvals, a simpler manual process is the safer choice.

Stitching it yourself or adding a proposed workflow

Zapier, Make, and n8n are the usual alternatives to a packaged tool: you connect a DMS export to QuickBooks Online or Zoho Invoice with a flow. When configured, these platforms can keep run histories, retry failed steps, branch on errors, and log each run, which is audit evidence many small teams never build. What they do not do is set your operating rules. You still design idempotency so a retry does not post the same invoice twice, decide who receives an error alert, control which accounts can hold the credentials, and maintain the flow when the DMS changes its export layout.

A design US Tech Automations could configure, labeled as proposed rather than deployed, starts when a deal is marked funded in a scheduled DMS export. The flow maps buyer name, vehicle identifier, price, fees, and tax lines into a draft invoice in your invoicing or accounting tool, and it writes one row to an exception log for any field that fails to map. Prerequisites are a DMS export or API read access that your DMS vendor enables, credentials for the accounting tool, and an agreed chart of accounts. The human review point is the sales or F&I manager, who approves each draft against the signed deal before anything is sent or posted.

A second proposed design watches for overdue invoices. Zoho's invoice status values include overdue, so the flow could read a status change, compare the due date, and create a reminder draft and a follow-up task for the office manager. The output is a draft and a task, not an automatic message. A person approves the reminder text, and the flow needs read access to invoices plus a rule for who sees the task.

Common mistakes buyers make

• Buying a general invoice tool for every deal and retyping data that the DMS already holds.

• Comparing a quote-only product with a published price as if the two were equal.

• Accepting a demo without a sample invoice generated from a closed deal.

• Missing per-contract or add-on fees that appear on the pricing page.

• Keeping records only in the invoicing tool and dropping the deal file; keep the deal file complete, including pre-listing checks like those in our recall status check workflow.

Four steps to choose

1. Confirm where each deal is closed. If the DMS holds the deal, shortlist DMS vendors. If not, shortlist general invoicing tools and budget for retyping.

2. Ask for a sample invoice and a sample accounting export from one closed deal, then check each line against the signed deal.

3. Get a written price that includes per-contract and add-on fees. For quote-only vendors, get a written quote before you compare.

4. Set retention. The IRS default is 3 years for records that support income and deductions, according to the IRS, with longer periods for listed exceptions.

Questions buyers ask before they sign

Is a free invoicing tool enough for a car dealership?

Usually not for deal paperwork, because free plans cap invoice volume and do not carry dealer deal fields. Use the plan limits in the pricing table above to check whether your volume fits. The free tier can still work as a supplement for invoices outside the DMS.

Do I need a dealer management system to issue car sales invoices?

No. A general tool can issue invoices, but you then rebuild deal details by hand, and that rebuilding is where errors enter the record.

Why do some vendors not list prices?

The pages we opened for DMS Complete, Tekion, and CDK Global route buyers to a demo or sales contact, so their prices are quote-based in this comparison.

How long should I keep the records?

The IRS default is 3 years for records that support income and deductions, and longer for the exceptions covered in step four above. Keep deal files and invoices for at least that long.

What should I ask for in a demo?

Ask for a sample invoice from a closed deal, the accounting export file, a list of every fee included in the price, and the retention setting for deal files. A vendor that cannot show those four items is asking you to buy on trust.

Where to go from here

Shortlist one DMS-based option and one general tool, run each through the four steps above, and keep the sample invoice and export as your evidence file.
