Wrenbase

For contractors & trades

One job.
Three invoices.
No spreadsheet.

You don't get paid once. You collect a deposit, draw at rough-in, finish, and bill the final. Send the invoice before the ladder goes back on the truck. Every invoice carries the same job reference. The homeowner sees one story. You see one running balance.

How trades actually bill

Bill in stages.
Get paid in stages.

Material drops Tuesday. Crew shows up Wednesday. Rough-in done Friday. The bill goes out Friday afternoon. The homeowner pays the next week. By the time you order the tile, the deposit covers it.

Wrenbase handles every invoice on the same job under the same name. You stop running a spreadsheet to remember what's collected and what's still out.

Same reference across invoices, requests, and vendor bills.

One reference, every record

The job number ties the whole record together.

Every invoice, payment request, and vendor bill carries a reference field. You decide what it means. A job number on a remodel. An engagement ID on a consulting retainer. A project code on a design brief. A PO number when procurement asks.

Filter by that reference and every related record lines up. The record is the work, not the invoice.

Trust on both sides

The homeowner sees the same numbers you do.

When your customer has an Invoice Inbox, every invoice you send lands there automatically. Same amounts. Same statuses. No reconciliation phone calls.

Cash Pulse

Do you know if this job made money? Are you ahead this month?

One ledger holds every deposit, invoice, material bill, and sub payout. Cash Pulse reads it and answers the two questions that actually matter: is this job in the black, and does the deposit cover the next material drop.

Your words, in Wrenbase

You keep your language. It maps underneath.

You don't learn accounting words to run a job in Wrenbase. What you already call things on the truck maps onto the ledger objects that make the margin add up.

The whole arc of a job

Estimate to final. Every step is a record.

A job rarely runs in one payment. It runs in stages, and so does the money. Wrenbase holds each step under the same job.

Every step threads the same job reference. Nothing gets rebuilt.

Subs and material suppliers get paid as vendors, their bills counted against the same job. When a draw needs a signed release before it funds, the paper trail is already sitting under the job.

Common questions

What every contractor asks.

Right now my jobs and invoices live in a notebook or a spreadsheet. What changes?
You stop running the job from a notebook. Each job lives in Wrenbase with every invoice you've sent against it, every payment you've taken, and the running balance you actually owe materials against. No flipping between a spreadsheet and a paper folder to figure out where you stand. If you've got a spreadsheet of past jobs or customers, drop it in and Wrenbase imports it.
How do I bill a deposit before I start the work?
Send a payment request for the deposit before kickoff. The homeowner pays by card, ACH, or whatever works for them. When it clears, you can order materials. The deposit sits under the same job as every invoice that follows.
How do I send a progress invoice without rebuilding the scope?
Open the job, hit New invoice, enter the amount for the current stage. The customer info, your branding, the job reference are already filled in. It takes a couple of minutes from your truck or your kitchen counter.
What if the homeowner pays a deposit by check?
Mark the invoice paid and pick the method. The invoice closes, the job's running balance updates. Your history stays complete whether the money came through Wrenbase or not.
How do I track what's collected on a job vs what's still owed?
Every invoice on a job shows up under the same view. Total billed, total collected, outstanding balance. The math is done for you.
Can I send an invoice from my phone?
Yes. Type the amount, pick the job, send it. The homeowner gets the email before you pull off the curb.
How do I show the homeowner a clean record of what's paid?
Every invoice carries your branding and the job reference. The homeowner sees a consistent set of bills they can reconcile against their own records. When the job is done, they have a complete paper trail without you having to assemble one.
What if the homeowner has a Wrenbase account of their own?
Every invoice you send lands in their Invoice Inbox automatically. All the bills for the bathroom remodel sit under one job with a running balance they can see. If they reference the job years later for a refi or a sale, the record is right there.
How do I handle bills from material vendors and subs?
Share your Intake link with your tile supplier, your electrician sub, your lumber yard. They submit a structured bill with PO and amount. The bill lands in your inbox, screened, ready to review. No more PDFs lost in your email.
Can I track job costs against what I billed?
Yes. Every job is a project: your invoices on one side, supplier and sub bills on the other, margin in the middle. You see where the job stands before it closes out, not after.

Stop running every job through a spreadsheet.
