ERP-light ops management for fiber contractors

Bill every foot, aerial or underground.

Foremen report production from the phone; the office invoices it at that customer's rate card the same week.

Start with your own data

from $349 a month; every band has every feature

A ten-crew fiber shop bills about $800,000 a month, much of it typed from texts weeks later. Erebuild stops that leak.

Built by a telecom contractor.
Every invoice line is checked against the rate card to the cent before it leaves.

From the pin to the invoice, in three steps.

Step 1
Drop a pin on today’s job.
A call, email or bid becomes one job number and one customer; that customer’s rate card prices everything after.
Northline Fiber Co.’s jobs list: 15 active jobs for five customers, each with its status and what has been invoiced so far, $48,933.80 on Rochester NW Valleyhigh.
Step 2
Foremen report from the phone.
PIN login, no app store, works offline. Quantities go against that customer’s rate card units, with materials used and photos stamped when and where taken.
Thursday’s report on Rochester NW Valleyhigh: 300 ft of directional bore at $6.06, 3 handholes at $315.25, 4 underground drops and 300 ft of conduit, $4,277.55 in all, with the photo and the rate card the prices came from.
Step 3
The office approves. The invoice comes from the report.
Each approved report is priced from that customer’s rate card and variant, combined with hand-added quantities and checked to the cent. The invoice number ties out to your accounting system, whichever one.
Five invoices out the door, $185,857.40 in all, each with its invoice number and, once paid, the payment reference that ties it back to the books. Nothing reaches this list until a person approves every report behind it.

Run all three on your own numbers. Start with your own data

Your customers each have a system. This one is yours.

Every ISP portal shows one customer’s slice. A sub working for three ISPs lives in three portals, none carrying its own rates, subs, reels or margin.

Built inside a working fiber contractor. Report to invoice, rate cards by customer and variant, and reel audit trails came from crews using them every day.
Tested against money. Invoice totals must equal their line items, and date and double-billing bugs have reproduction tests.
People answer. A feature request goes to someone who has run a fiber crew, and small changes ship in days.
Specific to the trade. Easement snapping, rates by mode and ISP, reel states and Sunday-to-Saturday weeks.

Northline Fiber Co. dashboard: production revenue, total footage, active jobs, pending review, and weekly production by division. — Northline’s dashboard: **$248,186** of production in 30 days from 34 approved reports, with 17 reports waiting for approval. What the owner sees before the first phone call.

What is in it, by workflow.

Every band has all of it. Nothing is sold by module or by seat.

Map of the job. Road-following routes and structures, progress span by span; easement layer as a toggle.
Field reports. Quantities, materials and photos stamped when and where they were taken.
Rate cards. By customer, variant and zone. Load a rate card PDF and AI reads it for a person to check.
Production to invoice. Priced from the report, checked to the cent, with an invoice number that ties out to any accounting system (QuickBooks Online syncs today).
Job profitability. Import your time-clock export (busybusy or any other). Where project codes match, hours and labor cost land on the job next to what it billed.
Reels and materials. An audit trail of what came in, what each report used and what is left.
Subcontractors. They report in the same app and are paid from statements at their own rates.
Fleet GPS. Your trucks on the map from Samsara today, with each day’s trail and inspection alerts.
AI readers. Rate cards, bids, invoices, photos and voice notes. Metered, switchable; a person approves anything touching money.

Job photos: a grid of pole, strand and right-of-way photos, each stamped with date, time, job number, street address and GPS. — **47 photos** on the Rochester NW job, each stamped on upload with day and time, job number, nearest street address and GPS point, so a photo answers when and where without anyone typing it.

The Financials card of the Rochester job: revenue, invoiced, hours, labor cost and labor margin. — The Financials card on one job: **$76,440.85** of revenue, **$48,933.80** invoiced, **308.0** hours from the time-clock export, **$14,169.60** of labor cost and an **81.5%** labor margin.

Priced on what you bill through it, not on seats.

Every band has unlimited office users, unlimited foreman accounts (employee or sub), every feature and a monthly AI allowance. Three worked examples:

	A $2M shop	A $10M shop	A $20M shop
Band	Up to $3M	$3M to $12M	$12M to $30M
List, monthly, annual billing	$349	$899	$1,799
Month to month	$419	$1,079	$2,159
Founding, first 15, 24 months	$249	$629	$1,259
AI included each month	$25	$75	$200
Setup	$0 (optional $750 working session)	$5,000	$10,000

$899 a month for a ten-crew shop is $90 a crew, about $3 a crew per working day. One mis-rated production report costs more than that.

How the band works.

Your estimate of a year’s billing picks the starting band. After that the band follows what you invoice through the product, checked quarterly on the trailing twelve months with a 10% buffer, never more than one band per quarter, with thirty days’ notice and the arithmetic. Annual prepay locks your band for the year and gets two months free.

A ten-crew shop’s stack, against one system.

	Today’s stack	Erebuild
Schedule and tasks	monday.com or Asana, 18 seats: $380–450 a month	Included
Time tracking	busybusy, 30 users: about $300	Keep it; its export becomes labor cost per job here
Field reports	Raken or Fieldwire, 18 users: $830–1,150	Included, with photos stamped when and where taken
Rate cards and invoicing	Spreadsheets and about 20 office hours a week	Included: production to invoice, invoice number tied out to your accounting
Total	About $1,500–1,900 of software plus the hours	$899 a month plus the time clock you already have

Per seat: $51–64 across the three example companies, below Fieldwire Business ($64), in line with Raken, and 2.5–3× monday.com Pro, which does none of the work.

Questions an owner asks.

Who owns the data?

You do. Export on exit (database dump and files) within ten business days.

Support hours?

A person answers 8am–5pm Central on weekdays, with an engineer on call for outages; priority support adds phone/chat, one-hour response and Saturdays.

Do subs use it?

Yes, from the same field app; sub statements price at the sub’s own rates and sub revenue is attributed from the report, not guessed.

What accounting system do I need?

Any. Every invoice carries a number that ties out to your books, whatever you run. QuickBooks Online syncs directly today; others by export.

Is there clock in and out?

No, and none is planned. Keep the time-clock app your crews already use (busybusy or any other). Its export loads here, and when the project codes match, the hours land on the right job with labor rates, so job profitability works now. Loading the export is optional.

We already have to report in our customer’s system. Why another one?

Their system shows their slice and nothing of yours. Erebuild is your record across every customer.

Does it show our trucks?

Yes, from your fleet GPS. Samsara connects today with your own token; trucks appear on the main map with the day’s trail per truck and inspection alerts. Other providers follow.

Which states?

The map’s easement layer covers Minnesota today, Florida and California next; the rest of the product works anywhere in the US.

How does the price change?

Only when what you bill changes, checked quarterly on the trailing twelve months, one band at a time, with notice and the arithmetic. Annual prepay locks it.

Is AI making decisions?

No. AI reads documents and photos and suggests; a person approves anything that touches money, pay or quantities; each AI feature can be switched off, and its use is metered.

What is coming next?

Four things are coming, none of them on the price yet. Coming: each ISP’s daily production file, as-built and redline package and invoice backup, produced from the one report your crew files. Coming: photo pass/fail on submit that learns from your office’s approvals and rejections. Coming: vendor pricing and purchase orders built from every quote, receipt and invoice. Coming: easement guidance in Florida and California, beyond Minnesota metro.

Security?

One database per customer, no shared tables, named subprocessors on a public list, and a security summary page.
