Collect Deposit vs COD vs Bill: New Customer Risk Decision Matrix

Why this matters

A new customer is an unknown credit risk. You have done work for them zero times, so you have no payment history to lean on. The structure you choose, deposit before you start, collect on delivery, or invoice on terms, determines how much of your money is exposed if they do not pay. Get it right and you protect cash flow without scaring off good customers. Get it wrong in the lax direction and you fund someone else's project; get it wrong in the rigid direction and you lose jobs to a competitor who was easier to buy from. The decision scales with the size of the job and the signals you can read about the customer.

This is not about distrust. It is about matching your exposure to the information you have. A small diagnostic for a homeowner who found you on a map carries different risk than a large materials-heavy install for a brand-new commercial account, and the payment structure should reflect that.

The situation

A new customer approves a job. Before the truck rolls, someone decides how money will change hands: a deposit to secure materials and commitment, cash/card on delivery at completion, or an invoice with net terms. The decision has to balance closing the sale against the risk of doing the work and never getting paid.

What is at stake

The exposure is the unpaid cost of work performed plus materials purchased. On a labor-only diagnostic, that exposure is small and a strict policy may cost you the job for no real protection. On a materials-heavy install, the exposure is your out-of-pocket parts cost the moment they are installed and non-returnable. The matrix exists to put friction where the money is and remove it where it is not.

Decision factors

• Job size and materials cost. The larger the non-recoverable spend, the stronger the case for a deposit before you start.
• Customer type. A walk-up residential customer, an established-but-new-to-you commercial account, and a referral from a trusted source carry different baseline risk.
• Recoverability of work. Can you walk away with most of your cost (uninstalled parts) or is it sunk the moment it is done (poured, cut, programmed)?
• Lead source and verifiability. A verifiable address, a real business with a footprint, and a warm referral lower risk; an anonymous lead with a cash-only request raises it.
• Red flags. Pressure to skip paperwork, reluctance to give a billing address, urgency that does not match the situation, or a request to start before any payment.
• Your cash position. A business that can float materials has more latitude than one that cannot.

The decision: options and when each wins

Collect a deposit before starting wins when the job carries meaningful non-recoverable cost: special-order or custom materials, a large parts list, or significant labor committed up front. The deposit should at least cover your materials exposure so that a walk-away leaves you whole on hard costs. Deposits are standard and expected on installs and projects; asking for one is not a red flag to a legitimate customer. Many states regulate the maximum deposit on home-improvement work, so confirm the cap before quoting one.

Collect COD (payment at completion) wins when the job is labor-dominant with low materials exposure and completes in a single visit: diagnostics, service calls, small repairs. You are exposed only for the duration of the visit, and the customer pays before you leave. Card-on-file or pay-at-the-door keeps the exposure window to hours. This is the default for ordinary residential service.

Bill on terms (invoice, net X) wins when the customer is an established commercial account with verifiable standing, a property manager or GC you can credit-check, or a referral from a trusted relationship where terms are the norm. Terms are a credit decision; extend them only when you have something to underwrite against. Never extend open terms to an anonymous first-time residential caller.

Red flags override the matrix: any of them pushes a job up one risk tier (toward deposit/COD) regardless of profile.

What to document

• The payment structure agreed, in writing, before work starts.
• The deposit amount and what it covers, with the refund/cancellation terms stated.
• For terms: who approved the credit, the limit, and the net period.
• The customer's verified billing address and contact.
• Any red flags noted and why the structure was tightened.
• Proof of payment or signed terms acceptance attached to the job record.

A clear, written payment structure presented at booking, not at completion, prevents the most common dispute: a customer who claims they never agreed to a deposit or to paying on the spot.
