Key takeaways
- A flat monthly fee should cover a stated number of pumps per year, with extra pumps billed at the per-pump rate and a clause that lets you change the interval based on measured levels.
- Card fees grow with the size of the bill while ACH is usually a flat fee per debit, so the cost gap is widest on large interceptor accounts. Check it against your own statement.
- A timestamped manifest with photos on every invoice speeds approval in accounts payable and answers "you never came" claims on overnight pumps.
- After any sale or change of control, get a new signed agreement and a fresh payment authorization from the current owner before the next pump.
Grease trap service billing works best when a written contract sets the pump-out schedule and the price before the first truck rolls, and also names how the restaurant will pay. For independent restaurants, that usually means a card or bank account on file, charged automatically after each service. Chains and franchise groups want an invoice with the manifest attached, routed into an accounts payable process that pays on terms. Haulers mostly lose money in situations the contract never addressed. The usual ones are an extra pump when the kitchen gets busier and a restaurant that changes owners between visits.
Grease Trap Service Billing: Fixed Monthly Fee vs. Per-Pump Pricing
There are two basic ways to price a grease trap pumping contract, and each puts the risk on a different party.
Per-pump pricing bills each visit after it happens. The price is usually based on the trap or interceptor's capacity plus disposal at the receiving facility. Your revenue follows the work, so more pumps mean more billing. The downside is uneven cash flow for you and a large, irregular bill for an owner who watches cash daily.
A fixed monthly fee spreads the year's planned service into equal payments. Owners like knowing the number, and you get steady deposits. In exchange, you take on the risk that the trap fills faster than you planned.
A Worked Example: When the Schedule Slips
Take an illustrative account. Assume a large in-ground interceptor on a quarterly schedule. Assume also a monthly fee set so that twelve payments add up to exactly four pumps at your per-pump price. Then the kitchen adds a fryer line, grease output climbs, and the trap needs pumping every two months instead of every three.
Under per-pump billing, you invoice six pumps for the year and get paid for all of them. Under the flat fee, you still collect the equivalent of four. You've done two pumps for free, which is a third of the year's work. The disposal charges for those extra loads come out of your pocket as well.
The fix is a hybrid. The monthly fee covers a stated number of scheduled pumps per year, and anything beyond that is billed at the per-pump rate. Two clauses keep it fair. A cadence review clause lets you change the interval when measured grease and solids levels show the trap filling faster than expected. A disposal pass-through clause adjusts your price when the receiving facility changes its rates. Record measured levels at every visit so any argument about the schedule rests on numbers rather than opinions.
Smaller hydromechanical traps under the sink get more frequent visits and vary less from one visit to the next, so a flat monthly fee suits them. Our guide to setting up monthly member billing for plumbing maintenance agreements covers the enrollment and renewal mechanics, which work the same way here.
Card, ACH or Invoice: What Restaurant Clients Will Accept
Independent restaurant owners tend to pay bills from their phones and manage cash closely. Many prefer to put vendors on a card. A card on file, charged after each service, gets you paid without chasing anyone. Visa and Mastercard have network rules for stored credentials and recurring charges, and your processor will tell you which consent records it requires. At minimum, get a signed authorization that covers:
- the amount, or the formula used to calculate it
- the service schedule
- whether unscheduled or emergency services can go on the same card
- how the customer cancels
Store the card in your gateway as a token. A paper form in the truck is a security problem waiting to happen.
Card-on-file charges are card-not-present transactions, and those generally cost more to process than a card tapped at a terminal. Our explainer on why keyed and card-not-present transactions cost more walks through the reasons. ACH debit usually costs less per payment, but it comes with a lag. A debit returned for insufficient funds can take days to surface, so you may learn about the problem after the next service is already on the calendar. ACH also requires the customer's authorization.
Run the Card vs. ACH Math on Your Own Statement
The two cost structures behave differently. Card pricing is mostly a percentage of the payment, so the cost grows with the size of the bill. Most processors price ACH as a flat fee per debit, which stays the same whether the restaurant owes for a small under-sink trap or a large interceptor. The gap is widest on the big interceptor accounts.
To see what that means for your route, pull last month's processing statement and divide total card fees by total card volume. That's your effective card rate. Multiply it by a typical monthly contract fee, then by twelve, then by the number of contract accounts you run. Repeat the exercise with your per-debit ACH fee. If the difference is large, steer card-paying accounts toward ACH or price the two methods differently.
A surcharging program is one way to price in the difference. It's permitted in many states but not all, and the card networks add their own disclosure and cap requirements. Dual pricing and cash discount programs are the alternatives. Before adding a fee line to a restaurant invoice, read the surcharge rules for plumbing invoices.
Chains work differently. Expect vendor setup paperwork, usually a W-9 and a certificate of insurance, along with purchase order numbers and net payment terms. Some groups pay with corporate purchasing cards. If you accept those, passing invoice detail with the charge can lower your cost, as explained in our guide to how Level 2 and Level 3 processing cuts B2B card costs.
Bundling Manifests and Compliance Paperwork With the Bill
Restaurants pay you partly to stay out of trouble with the local sewer authority. Many local grease control programs (often called FOG programs) require food service businesses to keep pump-out records and produce them at inspection. Some go further and require haulers to report service directly. Rules differ from one city or utility to the next, so check them where you operate.
That paperwork is also your strongest collection tool. Attach a service record to every invoice that includes:
- service date and time
- trap or interceptor ID and capacity
- gallons removed
- measured grease and solids levels
- condition notes, such as damaged baffles or missing lids
- disposal facility and manifest number
- before-and-after photos
A complete record gets paid faster because an AP clerk can match the bill to documented work. It also settles the most common dispute in this business. Many pump-outs happen overnight with nobody from the restaurant on site, and a manager later says you never came. A timestamped manifest with photos answers that claim. It's also the evidence you'll need if a card payment is disputed; our guide to chargebacks for services rendered explains what issuers look for.
For card-on-file accounts, send the manifest first. Then charge the card and print the manifest number on the receipt.
Billing Emergency Pump-Outs Outside the Grease Trap Service Agreement
A backup during the Friday dinner rush is the classic emergency. An inspector's notice with a short deadline is another. Neither should be billed at the contract rate unless the contract says so.
Spell out the terms in advance:
- what counts as an emergency
- your response window
- the after-hours rate and any minimum charge
- whether an emergency pump resets the regular schedule
Name the restaurant contacts who can authorize an emergency call, because the cook closing up for the night probably shouldn't be approving a premium charge. Charge the card on file only if the original authorization covers unscheduled services. Otherwise, get approval on the call and confirm it in writing by text or email. The approach in our article on collecting after-hours fees upfront applies here with little change.
A second emergency in a short period usually means the schedule is wrong. Use the cadence review clause to propose a new interval.
Restaurant Closures and Ownership Changes: Protecting Your Balance
Restaurants change hands often, and the interceptor stays in the ground through every sale. What happens to your contract depends on how the business was sold, what your contract says and the law in your state, so treat what follows as general information rather than legal advice.
In an asset sale, the buyer takes over the equipment, the lease and often the name, usually through a new legal entity. That buyer generally isn't bound by your agreement unless the contract was assigned to them or they sign a new one. When the buyer purchases the business entity itself, the company you contracted with still exists, and your existing contract may simply continue. From the curb, the two look identical: same sign, same kitchen, new faces. Either way, get a new signed agreement from whoever now runs the restaurant, and confirm the details with a qualified attorney.
Payment works the same way. After a sale or change of control, don't rely on the existing card or ACH authorization. The payment method on file may belong to the prior owner, and charging it for service after the handover invites a dispute. Before the next pump, get a fresh authorization from the current owner, tied to a card or bank account they control.
Watch for signs that an account is in trouble:
- a declined card or a returned ACH debit
- a manager who says the owner can't be reached
- shorter operating hours
- a "for lease" sign or a liquor license transfer notice
When you see them, move the account to payment before service. Our guide to late fees, reminders and next steps on unpaid plumbing invoices covers balances that are already overdue.
Contract terms help here too. Require written notice of a sale, closure or change of control, and make any open balance due on transfer. For small entities, ask an attorney whether a personal guarantee makes sense. If a buyer wants a clean trap at handover, schedule the final pump for the seller and collect at the time of service. Lien rights for this kind of work vary by state, so confirm with a qualified attorney before relying on them.
Food halls and strip centers often share one interceptor among several tenants. In that setup the landlord is usually the right bill-to, and the landlord recovers the cost through common-area charges. The collection steps in getting the landlord to pay the bill translate directly.
Scaling to Multi-Location Food Service Accounts
A regional group with many sites is a different customer from the same number of independents. Franchise locations are often separate legal entities. The franchisor may negotiate your program while each franchisee pays, so confirm the bill-to for every site in writing. Corporate-owned groups usually want one consolidated invoice with a line and a manifest for each location, plus a PO number at the top.
Your billing system has to tie every charge to a specific site and its trap ID. Keep route planning separate from billing dates. You can pump by geography for truck efficiency and still bill every location on the same day of the month.
A virtual terminal handles one-off keyed charges. Stored cards and scheduled billing run through payment gateways such as Authorize.net and NMI, and MannyPay also integrates with QuickBooks for reconciliation. MannyPay's payment setup for plumbing and service companies covers these options.
Before your next renewal cycle, pull a few active contracts and check each one for a price on extra pumps and a notice requirement for sales, closures and changes of control. Then read the payment authorization and confirm it covers unscheduled work. Fix whichever gap shows up most often first. If your processing costs need a second look while you're at it, request a free quote and a MannyPay specialist will respond within one business day.
