ALPHA AP · Accounts payable automation for construction

Nobody hired on to type invoices.

AP automation software for construction & trades

Every vendor invoice read as printed, coded to the job, routed for a one-click approval, and posted to your ERP with the PDF attached. Your team reviews instead of types.

From $475 a month · Fifteen minutes, on your invoices.

§ 01 · How it works

From inbox to posted payable. No typing in between.

Plenty of tools read an invoice. Fewer code it to your jobs. Fewer still post it into a construction ERP. Here is exactly what happens inside ALPHA AP, all four steps, including the parts most tools gloss over.

A coded, approved payable lands in your ERP.

The invoice posts to your system of record with the project, cost group, PO match, and approval already attached, PDF included. Nobody re-keys a line of it.

§ 02 · Purchase orders

Every invoice, matched to its PO.

Construction runs on commitments. ALPHA AP pulls your purchase orders and subcontractor commitments, amounts and line items, straight from your ERP, and checks every invoice against them before it reaches an approver. This is two-way matching against the PO and the commitment, the check most invoice tools skip.

No PO, or the wrong one? Flagged.

Invoices with no PO, or matched to the wrong one, are held before an approver ever sees them. From the flag, your AP team emails the vendor to reissue with the right PO, without leaving the app.

Over the commitment? Held.

Anything that would push a commitment past its committed or contract amount is held for a person to release, line by line and at the contract level. Nothing quietly overruns.

Change orders and progress claims, handled.

Multiple invoices against one commitment, billed out of order, each move on their own. A held invoice never blocks the ones behind it.

Billed to date, this claim, what's left.

Because the commitment comes from your ERP, ALPHA AP shows what a vendor has billed against the contract, the current claim, and the balance remaining, right beside the invoice.

§ 03 · Who it's for

The four desks an invoice crosses.

The ALPHA team at the Courtenay office

The Controller

Month-end stops being archaeology. Every payable hits the books coded, approved, and posted with its PDF attached, so a cleaner look at job costs no longer costs four weeks of catch-up. When the auditor asks for backup, the trail is one click.

The AP clerk

The fifty-invoice month that became three hundred lands on this desk. ALPHA AP takes the typing and leaves the judgment. You review the flagged ones instead of keying the clean ones: the stamp retires, and the piles stop growing.

The PM

One click in an email, from the truck. Approve it, hold it with a reason, or reject it, then get back to the site. No login, no "it's on my desk," and no AP clerk left guessing why you sat on it.

The Owner

Committed costs show up while the job is still running, not a month after the money left. You see the wrong number before it gives away the profit, and you got there without adding another body to accounting.

§ 04 · Your ERP

Posting into the construction accounting software you already run.

Our connectors are posting coded payables into maestro*ERP, Sage 50, and QuickBooks Online today. An approved invoice becomes a coded payable in your system of record, PDF attached, with nobody re-keying anything in between. Purchase orders, commitments, projects, cost codes, and tax codes flow in; approved payables flow back out.

Running something else? Tell us what you run, and we build the connector. No rip-and-replace: your ERP stays the system of record and ALPHA AP feeds it.

§ 05 · Canadian tax

GST, PST, HST, QST. Read as printed. Posted as fields.

Canadian sales tax is not one line, and construction books know it. ALPHA AP reads each tax exactly as the vendor printed it and posts it into its own field in your ERP. GST, PST, HST, and QST each stay separate the way your books expect, so nobody adds four taxes into a single total or splits them back apart by hand at month end, and a Quebec vendor's QST is taken straight off the invoice, not rebuilt from a rate table.

What is accounts payable software?

Accounts payable software takes over the manual work between a vendor invoice arriving and a posted, payable bill: reading the invoice, coding it, collecting the approval, and posting it to your accounting system. The best AP automation software fits how your industry actually buys. ALPHA AP is accounts payable software built for construction and trades: it codes every invoice to project, activity, and cost group, matches it to POs and commitments, and posts it to maestro*ERP, Sage 50, or QuickBooks Online, from $475 a month.

§ 06 · FAQ

Questions AP teams ask.

What is accounts payable automation?

Accounts payable automation is software that reads vendor invoices, codes them to the right account, routes them for approval, and posts them into your accounting system, so nobody types invoice data by hand. ALPHA AP is accounts payable automation built for construction: invoices are coded to project, activity, and cost group, and posted into your ERP with the PDF attached.

How do invoices get into ALPHA AP?

Point an AP email address at ALPHA AP and invoices flow in as vendors send them, nothing for the vendor to change. You can also drag and drop. A file carrying several invoices is split into individual records automatically, so a batch of fifty is fifty records, not one.

Will ALPHA AP code invoices to our structure?

Yes. It pulls your projects, cost codes, GL accounts, and tax codes from your ERP and pre-codes each vendor from what it learns. Every line stays editable before approval, so complex jobs where one vendor hits several codes are handled with a quick review, not forced into one fixed mapping.

What happens when the AI isn't sure, or an invoice is handwritten?

Anything uncertain goes to a review queue with the original PDF beside the extracted fields, so a person confirms before it moves. Nothing posts on a guess. ALPHA AP reads PDFs, scans, and handwriting; the messier the source, the closer the human review before approval.

How do approvals work?

Route by amount, vendor, or project. Set a default approver per vendor so nothing is picked by hand, or choose from your approval list on the fly, and chain several approvers in sequence, for example a manager and then whoever allocates job costs. One click in an email approves, holds, or rejects, from a desk or a phone, and reminders nudge whoever is sitting on one.

Does ALPHA AP handle purchase orders?

Yes. It pulls your POs and subcontractor commitments from your ERP and matches every invoice against them: no-PO and wrong-PO invoices are flagged, anything over the committed amount is held, and change orders and multiple invoices against one commitment are handled without a held invoice blocking the rest. See purchase orders above.

Do you do two-way or three-way matching?

Two-way. Every invoice is matched against the purchase orders and subcontractor commitments pulled from your ERP. Three-way matching adds a receiving report, which most construction workflows do not produce; if yours does, tell us on the call.

Which ERPs does it post into, and is the sync live?

maestro*ERP, Sage 50, and QuickBooks Online today. The sync runs through your ERP's API on a schedule you set, and a copy of the invoice PDF lands on the record inside your ERP. Multiple companies in one ERP are handled: pick the company when you process the invoice. Running something else? Tell us what you run, and we build the connector.

Where is our data stored, and for how long?

In Azure data centres in Canada. Invoices stay searchable for seven years by default, backups are included, and there is no server to run in your office.

What does setup look like, and what do you need from us?

Two to four weeks. Send a sample of your highest-volume vendors' invoices and give us a test company in your ERP; ALPHA's team builds and tunes the connection and the coding, and keeps the calls light on your people.

How much does ALPHA AP cost?

ALPHA AP starts at $475 a month, and pricing scales with invoice volume. Book a demo and you will get a straight number on the call. Setup is quoted up front and done by ALPHA's team.

Who installs and supports it?

ALPHA's own team in BC. We sync your GL, vendors, tax rules, and approval chart before go-live, and the same people who built your setup answer the phone after.
