How Contractors Get Paid Faster: ACH, Cards, and Deposits

Close the gap between the work and the cash

By Faizan Khan, Founder, TackOn LLC / BuildCrux6 min readNovember 2, 2026

If you want to know how contractors get paid faster, start by looking at the gap between the day a crew finishes work and the day the money lands in your account. For a lot of small GCs and remodelers that gap runs 30 to 60 days, and sometimes longer when a client decides your invoice can wait. That gap is where businesses with full schedules still run out of cash.

The fix is not one trick. It is a handful of changes to how you bill, what payment methods you accept, and how fast you send the paperwork. Done together they can pull weeks out of your receivables.

We build estimating and invoicing software for remodelers and small commercial GCs, and we talk to contractors every week about why payments stall. The pattern is almost always the same: invoices go out late, they are hard to read, and the client has no easy way to pay on the spot. This guide walks through what actually moves money faster, based on how working contractors run their billing.

Why payments stall on good jobs

Slow pay usually has nothing to do with whether the client likes your work. It comes from friction you built into your own billing. Here are the four causes we see most.

You invoice late

The work wrapped Friday and the invoice went out the following Thursday because you were on the next job. Every day between completion and the invoice is a day the client is not even thinking about paying. The clock on their terms does not start until they get the bill, so a late invoice pushes your cash back a full week or more before anyone has done anything wrong.

The invoice is hard to pay

If paying you means writing a check, finding a stamp, and dropping it in the mail, you have added days to every single invoice. Clients pay the easy bills first. When the only option is a check, your invoice sits in a pile until someone gets around to it.

The scope is fuzzy

When an invoice lumps everything into one line that says "construction work, $18,400," the client has a reason to call and ask questions before paying. Every question is a delay. A bill tied to a clear scope of work and a schedule of values gives them nothing to argue about.

You skipped the deposit

Starting a job with none of the client's money in hand means you are financing their project out of your own account from day one. By the time you bill, you are already behind. A deposit at signing flips that, so you are working with their money instead of yours.

The BuildCrux Method for getting paid faster

Getting paid faster is a system, not a nagging phone call. These five pillars cover the billing cycle from the first estimate to the final payment.

Pillar 1of the BuildCrux Method →

Start with an estimate the client can read

Faster payment starts before the job does. When your estimate is broken into clear line items instead of one lump sum, your invoices can mirror it later, and the client already understands what they are paying for. AI takeoff can turn a plan set into a first-pass line-item estimate you review and adjust, which gives you a billing structure to build on from day one.

  • Break estimates into trade or phase line items, not one total
  • Keep the same line items on the estimate and the invoices
  • Review and correct every AI-generated quantity before it goes to the client
Pillar 2of the BuildCrux Method →

Set payment terms before you start

Decide the deposit, the draw schedule, and the net terms in the contract, not in a text message halfway through the job. A written schedule of values tells the client exactly when each payment is due and how much. When the terms live in the signed agreement, there is no negotiating at invoice time.

  • Collect a deposit at signing on every job
  • Tie progress draws to milestones, not calendar dates
  • Write net terms (net 15 is better than net 30) into the contract
Pillar 3of the BuildCrux Method →

Invoice the day the milestone hits

The single biggest lever is speed. Send the invoice the same day the milestone is complete, while the work is fresh and the client is happy with it. Billing from your phone on site beats waiting until you are back at the office, because the office visit never seems to happen.

  • Generate the invoice from the estimate so you are not retyping
  • Send it the day the phase passes inspection or walkthrough
  • Attach photos of the completed work so there is no doubt
Pillar 4of the BuildCrux Method →

Bill change orders separately and immediately

Extra work that gets buried in the final invoice is the number one reason final payments drag. Price and sign the change order before the work starts, then bill it on its own. A client who approved the number up front has no reason to hold the whole invoice because of it.

  • Get written approval before performing extra work
  • Bill approved change orders as their own line or invoice
  • Never let unbilled extras pile up to the end of the job
Pillar 5of the BuildCrux Method →

Watch what is owed and chase it early

You cannot collect what you are not tracking. An aging report shows you which invoices are 15, 30, or 45 days out so you call before an account goes cold. A short friendly reminder at day 10 collects more than a frustrated call at day 50.

  • Review invoice aging every week
  • Send an automatic reminder a few days before the due date
  • Flag anything past terms and make the call that day

Payment methods compared

The method you offer changes how fast you get paid. Checks are the slowest option still in wide use. Here is how the common ones stack up for a contractor.

Speed and cost vary by processor. ACH is usually the cheapest fast option for big invoices.

MethodTypical speed to your accountCost to youBest for
Paper check3 to 10 days plus mail timeFreeClients who refuse anything else
ACH bank transfer1 to 3 business daysLow flat feeProgress draws and large invoices
Card payment1 to 2 business daysPercentage feeSmaller invoices and deposits
Tap to pay on site1 to 2 business daysPercentage feeCollecting at the final walkthrough
CashImmediateFreeSmall jobs, record it carefully

For a $20,000 progress draw, the percentage fee on a card gets expensive fast, so ACH is usually the smart default on large amounts. For a $1,200 punch-list invoice, card or tap to pay at the walkthrough collects you on the spot and the fee is minor. Offer both and let the client pick.

Consider a two-crew remodeler running mostly kitchen and bath jobs in the $25K to $60K range. They were averaging about 40 days from invoice to payment. Every bill was a Word template redone from the estimate, mailed, and paid by check whenever the homeowner got to it.

They made three changes. They started collecting a deposit at contract signing. They moved to digital invoices with an ACH pay link. And they billed each phase the day it passed walkthrough instead of waiting for the office.

Within a few months their average collection time dropped under 20 days. The deposit alone meant they stopped floating material costs out of their own pocket. The ACH link turned out to be the quiet winner, since homeowners who would have let a check sit for a week paid online the evening they got the bill.

BuildCrux is built to close the gap between finishing work and getting paid. Your estimate line items flow into invoices so you are not retyping anything, and you can send a digital invoice with a pay link from the field. The invoices feature handles the billing, and ACH payments let clients pay large draws cheaply and fast.

On the front end, AI takeoff reads a plan set and gives you a fast first-pass line-item estimate you review and adjust before it goes out. That same line-item structure is what makes your later invoices clear and easy to pay. On the Office tier and up, AIA progress billing handles draw-by-draw billing with a proper schedule of values, so progress payments stop being a monthly scramble.

If you are weighing tools, our honest software comparison and the BuildCrux vs CompanyCam breakdown lay out where each one fits. CompanyCam is strong on jobsite photos; BuildCrux is built around estimating, invoicing, and getting paid.

Compare BuildCrux and CompanyCam

What is the fastest way for a contractor to get paid?+

The fastest practical path is a digital invoice with an ACH or card pay link, sent the same day the milestone is complete. ACH usually lands in your account in 1 to 3 business days and costs far less than a card fee on large invoices.

Is ACH or card better for contractor payments?+

Use ACH for large amounts like progress draws, because it is cheap and fast. Use card or tap to pay for smaller invoices and deposits where the convenience matters more than the percentage fee. Offering both lets the client choose and removes an excuse to delay.

Should I charge a card processing fee to the client?+

Some contractors pass the card fee to the client and keep ACH free as the no-fee option. That nudges clients toward the cheaper method for you while still giving them a card choice. Check your state rules and your processor's terms before adding a surcharge.

How big a deposit should I collect?+

Enough to cover your initial material purchases and mobilization so you are not financing the job from your own account. Many remodelers collect a deposit at signing, then bill progress draws tied to milestones. Keep deposits within what your state licensing rules allow.

How do I get clients to pay change orders without holding up the whole job?+

Price and get written approval before doing the extra work, then bill the change order on its own invoice instead of burying it in the final bill. A client who already signed off on the number has no reason to hold payment. Our change order guide covers the full process.

Does AI estimating help me get paid faster?+

Indirectly, yes. AI takeoff gives you a first-pass line-item estimate you review and adjust, and those same line items carry into clear invoices the client can read and pay without questions. It does not replace your review of the numbers.

How contractors get paid faster comes down to four habits: collect a deposit up front, invoice the day the work is done, make it easy to pay with ACH or card, and track what is owed every week. None of them require a bigger backlog. They just pull weeks of waiting out of the business you already have.

Start with the one that costs you nothing: send the invoice sooner. Then add a pay link and watch how much faster the money shows up.
