Invoice Follow-Up & Collections

Get paid without chasing.

Unpaid invoices don't usually mean unhappy customers — they mean busy ones. But every week an invoice sits unpaid, your cash flow tightens, and the follow-up call gets more awkward. So it gets postponed, and the problem compounds.

Zeitwerk builds collections systems for Toronto and GTA businesses that follow up automatically: polite, personalized reminders across email, SMS and AI voice, paced and escalated deliberately, with full tracking of every touch. Your team only steps in when a case genuinely needs a human.

Serving Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill and the rest of the GTA — on-site or remote.

The cost of not chasing

  • Receivables age because follow-up depends on someone remembering to do it.
  • The same generic reminder goes to every customer, regardless of history.
  • Staff dread collection calls, so they happen late — or not at all.
  • You have no clear picture of which invoices were chased, when, or with what result.
  • Cash flow suffers even though the work was done and the customers are willing to pay.

If any of this sounds like your operation, it's not a staffing problem — it's a workflow that was never designed to scale. That's what we fix.

How it works

Every engagement follows the same disciplined path: understand the workflow first, then engineer the automation around it — never the other way around.

01

Connect your receivables

We hook into your invoicing or accounting system so the automation always knows what's outstanding, what's overdue and what's been promised.

02

Design the cadence

Together we set the tone and pacing: friendly nudge, firm reminder, escalation. Different customers and amounts can follow different paths.

03

Automate across channels

Reminders go out by email, SMS or natural AI voice call — personalized to the customer and invoice, never a one-size-fits-all blast.

04

Escalate only what matters

Disputes, hardship cases and silence past your threshold get routed to your team with full context. Everything else resolves itself.

Built for businesses with real receivables

  • Property managers and landlords collecting rent at scale
  • Trades and contractors with net-30 invoices that drift to net-90
  • Agencies and professional services tired of chasing retainers
  • Any Toronto or GTA business where receivables outrun collections time

Frequently asked questions

Won't automated collections annoy my customers?+

Done crudely, yes — which is why we calibrate tone and pacing with you before anything goes out. Polite, well-spaced, personalized reminders are far less irritating than a tense phone call after ninety days of silence, and customers respond to them.

What channels can it use?+

Email, two-way SMS and natural-sounding AI voice calls, in whatever combination fits your customers. Messages adapt to the customer and the invoice rather than following one static script.

When does a human get involved?+

Whenever you decide: disputes, promised payments that lapse, sensitive accounts or balances past a threshold you set. The system hands your team the full history, so the conversation starts informed.

Does this work with our accounting software?+

We integrate with the invoicing and accounting tools you already run, so outstanding balances stay in sync and payments automatically stop the reminders.
