Deposits and payment terms: you are financing your customers, and it was never a decision

Terms that actually get honored

"Net 30" written on an invoice is not a term; it is a hope. Terms are honored when four things are true:

• They were agreed before the work started, in the same document that describes the scope and the price.
• The invoice is delivered immediately, ideally the same day, with the work described in the customer's language rather than in job codes.
• The consequence exists and is known — a late fee if permitted in your jurisdiction, a hold on further work, or suspension of service — and it is applied consistently rather than selectively.
• Paying is effortless. Card, transfer, link, mobile payment at the door. Every added step is a delay, and delay is how receivables age.

Commercial work: different rules entirely

Residential customers usually pay quickly when asked. Commercial customers pay on their own schedule, and that schedule is a system rather than a decision. Four adjustments are needed:

• Find out how their accounts payable actually works before the first job: who approves, what documentation is required, what the payment run schedule is, and whether a purchase order number must appear on the invoice. An invoice missing a PO number can sit for a full cycle without anyone being at fault.
• Price the delay in. Work paid at 45 or 60 days costs you working capital, and that cost belongs in the price, not in the owner's stress.
• Invoice with their process in mind — correct reference numbers, itemization at the level their system expects, and delivery to the person who processes rather than the person who requested the work.
• Escalate early and politely. A friendly check three days after the due date resolves most commercial delays, which are usually clerical rather than financial.

When it goes wrong: the escalation ladder

Collections work best as a defined sequence applied automatically, rather than as a decision the owner makes when annoyed:

• Day 1 after due: automated reminder with the invoice and a payment link.
• Day 7: a phone call, friendly, assuming an oversight. Most balances resolve here.
• Day 15: a call to whoever authorized the work, with a specific question — is there a problem with the work, or is this a process issue? — because the answer changes what to do next.
• Day 30: written notice with the terms, the consequence and a firm date.
• Day 45+: stop further work for that customer and move to the formal path available to you. Lien rights, notice requirements and deadlines vary enormously by state and are frequently strict — if your work is lienable, those deadlines must be tracked from the start of the job, not discovered at day 45.

The judgment that matters most in this ladder is early: when a customer disputes quality to avoid payment, resolve the quality question first and separately. Mixing the two conversations gives the customer a reason to keep both open indefinitely.

A year in numbers

An eleven-person service company with $1.3M revenue, no deposit policy, invoices sent weekly in a batch, and terms described verbally.

• Q1: baseline. Days sales outstanding at 52. Write-offs running at 1.9% of revenue. Two payroll periods covered by a line of credit.
• Q2: same-day invoicing introduced; payment link added. DSO falls to 38 with no other change.
• Q3: materials deposit standardized on jobs above $2,000, milestone billing for anything above $12,000. DSO at 27.
• Q4: escalation ladder automated. DSO at 21, write-offs at 0.6%.

Moving DSO from 52 to 21 days on $1.3M of revenue frees roughly $110,000 of working capital — money that was always the company's and was simply sitting in customers' hands. The write-off improvement adds about $17,000 of recovered revenue on top.

The most instructive part is that the largest single gain came from the cheapest change: invoicing the same day instead of weekly, which alone removed fourteen days. No conversation with a customer, no policy change, no confrontation — just removing the delay the company had added itself.

Financing and payment options: selling the job, not the price

A large share of lost service jobs are not lost on price — they are lost on affordability, which is a different problem with a different solution. Three options address it without discounting:

Consumer financing through a third party. The customer pays monthly, the company is paid in full within days, and the provider takes a fee that must be priced in rather than absorbed. It converts a $9,000 objection into a monthly figure the customer can evaluate against their budget, and it is standard practice in several trades for exactly that reason.

Staged scope. Doing the urgent portion now and the rest in a defined second phase. It is honest, it protects the relationship and it frequently produces more total revenue than the single quote would have, because the second phase is sold to a customer who already trusts you.

Card on file for maintenance agreements. Recurring work billed automatically removes collection entirely from a whole category of revenue and improves retention, because cancelling requires an action rather than simply not paying.

The card processing and financing fees are real and should be treated as a cost of doing business, priced into rates the way materials and burden are. Companies that add a surcharge instead should check the rules that apply — surcharging is restricted or regulated in a number of states and by card network rules — and should weigh whether the friction at the moment of payment is worth the recovered percentage.

What the written agreement must contain

Most payment disputes in service work trace back to a document that described the price but not the deal. Beyond scope and price, six items belong in every agreement, and none of them makes the paperwork adversarial:

• Payment schedule, with amounts and the exact trigger for each — a date, a milestone or completion.
• What completion means, in objective terms, so the final payment has an unambiguous trigger.
• Change order process: that changes will be priced and approved in writing before being performed. This single clause prevents the most common dispute in the trades.
• Conditions found, listing the discoveries that are foreseeable in your work with the price of each if encountered.
• Consequences of late payment, to the extent permitted where you operate.
• Warranty terms, which belong in the agreement rather than being remembered differently by each party later.

Home improvement contracts are specifically regulated in many states, with requirements around written contracts, deposit limits, cancellation rights and mandatory disclosures — these vary substantially and must be verified locally rather than copied from a template found online.

Six mistakes that keep service companies waiting for money

• No deposit on jobs with purchased materials. The company finances the customer's project without interest.
• Batching invoices weekly. Adds days to every payment for administrative convenience.
• Verbal terms. Unwritten terms are unenforceable in practice and forgotten in good faith.
• Consequences that are never applied. A late fee that is always waived teaches customers the due date is optional.
• Making payment inconvenient. Every extra step delays money that was ready to move.
• Letting a quality dispute and a payment dispute merge. Separate them, resolve the quality question, then collect.

Five numbers to track

Five metrics control cash in a service business. Days sales outstanding, monthly, which is the headline measure of how much you are financing for others. Days from completion to invoice, the cheapest number to fix and usually the largest single lever. Percentage of jobs with a deposit collected, where the policy applies. Aging buckets — current, 30, 60, 90 — watched for the shape rather than the total, since a growing 60-day bucket predicts a write-off months in advance. And write-offs as a percentage of revenue, which is the score for the entire system and, in a healthy residential service company, should sit well under 1%.

Frequently asked questions

Should a service business take deposits?

Yes, and asking is a process question rather than a trust question — customers already pay deposits everywhere else. Three structures cover most service work. A materials deposit covering what must be bought specifically for that job, which is easy to justify because custom-ordered material cannot be returned to the shelf. A percentage deposit with milestones for larger projects, where the milestone must be objective and visible — rough-in complete rather than 50% done. And payment on completion collected the same day for short service work, which performs best when it is expected as a normal part of finishing rather than mentioned for the first time at the door. The wording that works is matter-of-fact policy rather than per-customer negotiation. Deposit rules and limits for certain work, particularly home improvement contracts, are regulated in some states and must be verified locally.

What makes payment terms actually get honored?

Four conditions, and Net 30 written on an invoice satisfies none of them by itself. The terms were agreed before the work started, in the same document that describes scope and price. The invoice is delivered immediately, ideally the same day, describing the work in the customer's language rather than in job codes. The consequence exists and is known — a late fee where permitted, a hold on further work, or suspension of service — and it is applied consistently rather than selectively, because a fee that is always waived teaches customers that the due date is optional. And paying is effortless, with card, transfer, link or mobile payment available at the door, since every added step is a delay and delay is how receivables age.

How is getting paid different with commercial customers?

Commercial customers pay on their own schedule, and that schedule is a system rather than a decision, which requires four adjustments. Find out how their accounts payable actually works before the first job: who approves, what documentation is required, what the payment run schedule is, and whether a purchase order number must appear on the invoice — an invoice missing a PO can sit for a full cycle without anyone being at fault. Price the delay in, because work paid at 45 or 60 days consumes working capital and that cost belongs in the price. Invoice with their process in mind, with correct reference numbers and delivery to the person who processes rather than the one who requested the work. And escalate early and politely, since a friendly check three days after the due date resolves most commercial delays, which are usually clerical.

What should the collections process look like?

A defined sequence applied automatically rather than a decision made when the owner is annoyed. Day one after due: an automated reminder with the invoice and a payment link. Day seven: a friendly phone call assuming an oversight, where most balances resolve. Day fifteen: a call to whoever authorized the work asking a specific question — is there a problem with the work, or is this a process issue — because the answer changes what to do next. Day thirty: written notice with the terms, the consequence and a firm date. Day forty-five and beyond: stop further work and move to the formal path available to you. Lien rights, notice requirements and deadlines vary enormously by state and are frequently strict, so if your work is lienable those deadlines must be tracked from the start of the job rather than discovered at day forty-five.

Does offering financing help a service business?

It addresses a different problem than price. A large share of lost jobs are lost on affordability rather than cost, and three options solve that without discounting. Consumer financing through a third party lets the customer pay monthly while the company is paid in full within days, with a provider fee that must be priced in rather than absorbed. Staged scope — doing the urgent portion now and the rest in a defined second phase — is honest, protects the relationship and frequently produces more total revenue, since the second phase is sold to a customer who already trusts you. And a card on file for maintenance agreements removes collection entirely from a category of revenue while improving retention. Processing and financing fees are a cost of doing business and belong in the rate; surcharging is restricted or regulated in several states and by card network rules.
