The Complete Guide to Restaurant Invoice Approvals

Most groups I talk to have automated the first step and stopped. Invoices get photographed or emailed into a tool, and then a GM still approves them one by one in a queue, corporate still pays from three checkbooks, and nobody can tell you what the group owes Sysco this week. This guide is the whole workflow, with the controls that make it safe to hand off.

Why do restaurant invoice approvals break down as a group grows?

At one location, the owner sees every invoice and knows every vendor. Approval is a glance. At three or more locations, the same glance becomes a bottleneck, and the ways it breaks are consistent:

• Paper and email intake. Invoices arrive on the delivery truck, in a GM's inbox, and in a vendor portal. Some get entered twice, some never get entered, and the ones that never get entered surface as a vendor call or a credit hold.
• Coding by whoever is available. Produce lands in COGS at one store and in supplies at another. Comparability dies, and so does your ability to spot price creep.
• Approval by inbox. Every invoice waits for a human, so the human approves in batches without reading, which is worse than no approval at all.
• Payments from multiple accounts on multiple schedules. Vendors get paid early at one store and late at another. Early payment discounts get missed. Cash is trapped in float.
• No group-level AP view. The owner can't answer "what do we owe, to whom, when?" without calling each store.

Step 1: How should invoices come in?

Every invoice, every location, one intake. In practice that means a dedicated AP email address per location that forwards into your AP tool, a mobile app for the invoices that arrive on the truck, and direct connections for the vendors that can send electronically. The intake tool should extract the vendor, invoice number, date, line items and totals using OCR, and flag duplicates by vendor and invoice number so a re-sent invoice doesn't get paid twice.

The rule to enforce: an invoice that didn't come through intake doesn't get paid. That single rule eliminates most of the leakage.

Step 2: How should invoices be coded?

Coding is where the group-level reporting is won or lost. Two rules:

1. Location is assigned at intake, from the inbox it arrived in or the store on the delivery ticket, never by asking the approver.
2. GL account is assigned by vendor default and line-item rules, not by the person approving. Your produce vendor codes to produce COGS. Your linen vendor codes to linen. Exceptions get flagged, not hand-coded.

Line-item detail matters more than most operators expect. If the tool captures the case price, you get price-per-unit tracking across stores, which is how you find out that one location is paying, say, 12 percent more for the same chicken. Tools like MarginEdge and Ottimate do this well, and it's why we include invoice capture in FIXE's standard plans rather than treating it as an add-on.

Step 3: What should the approval rules look like?

Approval should be a rule set, not a queue. The rules do the routine work and humans handle the exceptions. A workable starting rule set for a group:

That last row is the one that prevents the expensive mistake. Vendor payment fraud often starts with an email asking you to update banking details. Nothing in your AP process should be able to change where money goes without a phone call to a number you already had on file.

Step 4: How should supplier payments run?

One weekly payment run, from one place, covering every location. The bookkeeper pulls everything approved and due, the owner reviews a single payment summary by vendor and location, and payments go out by ACH or virtual card wherever the vendor accepts it, with checks only where you have no alternative. The benefits stack up fast:

• Vendors get paid on a predictable day, which is worth real money in relationship terms.
• Early-payment discounts get captured because someone is looking at terms in one list.
• Cash is managed at the group level, so you aren't floating one store while another sits on excess.
• The AP aging report is true, because everything owed is in one system.

Weekly vendor payments are part of FIXE's standard service for exactly this reason: the group gets a single payment run and a single view of what it owes, and every payment is recorded in your books.

What controls should stay in place once it's automated?

Automation removes the daily work. It shouldn't remove oversight. Keep these four controls and review them monthly:

1. Separation of duties. The person who approves invoices shouldn't be the person who releases payments, and neither should be able to add a vendor alone.
2. A weekly exceptions review. Fifteen minutes on what the rules flagged: variances, new vendors, duplicates.
3. A monthly vendor spend review by location. Price per unit across stores, spend by category, and anything that moved more than a few percent.
4. A quarterly rule review. Thresholds and vendor defaults drift. Adjust them on purpose.

Frequently asked questions

How do restaurant groups automate vendor invoices and supplier payments?

By capturing every invoice digitally through one intake per location, coding location and GL account automatically from vendor defaults and line items, approving through rules based on amount and variance rather than manual queues, and paying on one scheduled weekly run from a consolidated view of what's owed. The approval rules and the single payment run are the parts most groups skip, and they're the parts that make the rest safe.

What is a reasonable approval threshold for a restaurant group?

It depends on your volume, but a common structure is: auto-approve recurring vendors within a variance band, route anything over a fixed amount (often $1,000 to $5,000 depending on group size) to an owner or director, and always hold new vendors and bank-detail changes for verification. Start conservative and loosen as the rules prove out.

Should each location pay its own vendors?

No. Centralize payments even if invoices are approved locally. A single weekly run gives you consolidated cash management, a true AP aging, and more negotiating power on group volume. Location managers still see their own invoices and spend; they just don't hold the checkbook.

How do you prevent duplicate or fraudulent vendor payments?

Duplicate detection by vendor and invoice number at intake, a hard rule that unrouted invoices don't get paid, verified vendor setup with a W-9, and a callback to a known phone number before any change to bank details. Separate the roles of approving invoices and releasing payments so no single person can do both.

Does FIXE handle invoice processing and vendor payments?

Yes. FIXE is restaurant bookkeeping software with the bookkeeper included. Invoice capture, coding, and accounts payable automation are included in every FIXE plan, and weekly vendor payments are part of the standard service. Operators get a single view of what the group owes and a single weekly payment run, with every payment recorded in the books. Details are on the pricing page.
