Why Admin Army Recommends Trades Businesses Invoice Directly Out of Fergus (Not Accounting Software)

Fergus

“If it’s ready to be invoiced, why aren’t you sending it?” Irene Bennetts, CEO & Founder, Admin Army

Admin Army is an outsourced finance team supporting small and medium businesses with bookkeeping, payroll, and compliance.

And for trades businesses in particular, Irene Bennetts has seen the same pattern play out hundreds of times:

Good operators. Great work.

But invoicing is late and so payments are late, which means cash flow stays tight.

This is the operational fix Admin Army recommends most often:

Run the job in Fergus. Invoice in Fergus. Sync to Xero for accounting.

Built for operations, not just accounts

Admin Army doesn’t only “do the books.” They get deep into workflow – because the goal is operational efficiency.

The focus is simple: reduce admin, tighten process, and free the owner from being the system.

That’s why Irene cares so much about invoicing behaviour. It’s not a finance preference. It’s a business operating decision.

The reality Irene sees before Fergus

In trades, invoicing tends to land in one of these patterns:

  • Invoices sent once a week (“Thursday night invoicing”)
  • Invoices sent once a month (often after memory has faded)
  • Invoices sent way too late (“oh crap, I forgot to invoice that job”)

And the downstream impact is predictable:

Cash flow becomes a waiting game

If the invoice isn’t sent, it can’t be paid and most trades are already carrying wages + materials before money lands.

Margin leaks quietly

Small misses stack up: uncharged materials, missed labour, variations that never got formalised. The job was “busy”… but profit tells a different story.

The owner stays stuck in the weeds

Instead of running the business, they’re doing admin after hours.

The shift: Thursday night invoicing → 10 minutes a day

Irene’s best clients don’t do marathon invoicing sessions.

They move to a daily rhythm:

  • Time entries captured properly
  • Back-costing kept current
  • Invoice drafts ready when the job is ready
  • Owner reviews quickly and sends

The outcome is simple: Invoice sooner → get paid sooner.

Before & After: What Changes

BEFORE FERGUS • 2 hours invoicing Thursday night • Weekly or monthly batching • Missed costs on every job • Owner stuck doing admin

AFTER FERGUS • 10 minutes daily invoice review • Invoice when job is ready • Clean job costing, nothing missed • Owner focuses on growth

Real example:

One of Admin Army’s clients was spending two full hours every Thursday night trying to remember what happened all week – materials logged in notebooks, time entries half-remembered, some jobs forgotten entirely.

After moving to daily updates in Fergus, invoicing dropped to 10 minutes a day, missed costs went from “every job” to “rarely,” and cash flow improved by cutting the invoice-to-payment cycle by an average of 8 days.

The “invoice out of Fergus” rule (and why it matters)

This is the core idea Irene reinforces:

Invoices should originate where job truth lives.

For job based work, that “truth” is:

  • Labour (time entries)
  • Materials
  • Job status / stages
  • Scope changes / variations

When an invoice is created in Fergus, it’s automatically anchored to the job record, keeping all job context aligned. Starting the invoice in Fergus helps ensure everything stays connected and easy to track from the outset.

This is the same logic Fergus highlights in other customer stories.

What changes when invoicing runs through Fergus first

1) “Ready to invoice” becomes obvious

Instead of relying on memory, the system shows what’s ready.

2) Job costing stays intact

You keep the connection between:

  • What it cost
  • What you charged
  • What margin you made

3) Fewer things fall through the cracks

This is the big one: the tiny misses that erode profit without anyone noticing.

What payment behaviour typically looks like (what Irene sees)

Across many trade businesses, Irene describes payment speed as “tiered”:

  • ~50% of invoices paid within 7 days
  • Another ~30% paid within the month
  • The remaining ~20% varies depending on who you invoice (especially B2B payment cycles)

This is why Irene pushes daily invoicing: you can’t control every payer, but you can control how fast invoices leave the building.

What a clean trades workflow looks like (Irene’s $15K example)

For a mid-sized job (e.g., ~$15k), Irene recommends a system that protects cash flow:

Step 1: Quote + acceptance in Fergus

Keep the job lifecycle in one place with Fergus quoting.

Step 2: Deposit up front (ideally 50%)

Because the deposit covers base costs (wages, materials) and reduces the “you financed the whole job” problem.

“Your cash flow should work for you, not you working for your client’s cash flow.”

Step 3: Stage-based invoicing

If the job has phases, phases should have payment points.

Fergus supports progress invoicing tied to job stages.

Step 4: Keep costs current (daily updates)

This keeps invoicing simple and reduces end-of-job surprises.

Mobile teams can use Fergus Go to log time and materials on-site.

Step 5: Use variations properly

If scope changes, don’t let it float as a verbal agreement. Record it, price it, and invoice it – so margin doesn’t get eaten by “extras.”

Fergus handles variations and change orders within the job record.

“But can’t I just invoice out of Xero?”

You can. But Irene’s view is: it depends what you’re building.

If you’re staying solo forever with very simple jobs, Xero Projects might work.

But if you’re building a scalable operation, one that runs without you, that has a team, that protects margin-invoicing from the accounting layer creates friction you don’t need:

  • Less job visibility
  • Harder to keep costing accurate
  • Higher chance of missed items
  • Harder to standardise across a team

This mirrors the workflow Fergus customer stories consistently recommend: job management is the operational backbone; accounting is the system of record.

Even Xero recommends using connected apps from the Xero App Store for job-based trade workflows.

What the best Fergus customers do differently

The “great” ones aren’t magical – they’re consistent:

  • They update jobs daily (time, materials, notes)
  • They keep back-costing current
  • They invoice when ready – not on a weekly schedule
  • They handle variations cleanly
  • They reduce owner bottlenecks by systemising the workflow

That’s how “two hours on Thursday night” becomes “ten minutes a day.”

Who this is best for

This workflow is strongest for trade businesses that:

  • Run multiple jobs per week
  • Have a team (or want one)
  • Care about job margins
  • Want cash flow to be predictable, not stressful

It’s less critical for ultra-low-volume operators with very simple work, but even then, most businesses grow into needing it.

Final word

If you take one principle from Irene’s perspective, it’s this:

Invoice from the job system – because that’s where the job truth lives.

Fergus helps standardise the operational workflow (quote → job → costs → invoice).

Xero stays clean and accurate as the accounting system.

And the result is what every trade business wants:

Faster invoicing, tighter margins, and fewer cash-flow surprises.

If you’re tracking jobs, labour, and materials in Fergus, you should invoice in Fergus – then sync to Xero for accounting. Fergus is designed for job-based quoting and invoicing, while Xero is designed for accounting, reporting, and reconciliation.

It means the invoice is created inside Fergus (from the job record) and then sent to Xero through the integration. This keeps the invoice aligned with job labour/material costs and job status.

Yes-Fergus provides an integration that can send customer invoices to Xero and sync relevant data between the two platforms, reducing manual data entry.

Setup guide: Integrating with Xero

You can use Xero Projects to track time/costs and invoice project work inside Xero. But Xero also recommends connected job/invoicing apps through the Xero App Store, which is often a better fit for trade workflows where job management needs to be front-and-centre.

Sending invoices late (or in batches) is the biggest mistake-because it delays cash flow and increases the chance costs get missed. A job workflow that makes “ready to invoice” obvious helps tradies invoice sooner and capture more chargeable items.

Not always. For small jobs, deposits can feel unnecessary. For larger jobs, deposits protect cash flow and help cover base costs like labour and materials while work is underway. Fergus supports deposit and split invoicing workflows.

Invoice as soon as the job is ready and, where appropriate, take payment on-site. Fergus supports mobile invoicing workflows in Fergus Go, and Tap to Pay options can reduce payment delays by collecting payment immediately.
