Hi Dana, a quick note on INV-00377 for the March service visits, now 14 days past due. I've attached the invoice and the signed work orders again. Could you let me know when it's scheduled?

Cash gets stuck in four places. duebird clears each one.

Between the work and the money, every invoice crosses four handoffs. Each is where B2B teams lose days.

  1. Work done

    Nothing left unbilled

    Deliveries, milestones and usage wait for a month-end pile, and some never get billed.

    See where a line comes from
  2. Invoiced

    Invoices AP can't send back

    Their AP sends it back: wrong PO number, unknown item code, backup missing.

    See what they receive
  3. Accepted by AP

    Follow-ups that know the account

    Reminders go out late, generic, to the wrong person, or into a live dispute.

    Step through a month
  4. Paid

    Every dollar in its place

    One deposit, four invoices, a credit and a bank fee. Short pays turn into mystery balances.

Every line shows its source, and its math

Quantities come from the paperwork, prices from their PO and your price lists, and the arithmetic is calculated. Pick a line, then a number.

It reads the whole account before it writes a word

Every morning it checks five things on each open invoice, then chases, waits, holds or stays quiet. Step through Northline's month.

What was said before
Continues the 13 Oct thread, so it reads as the next line of that conversation.

Hi Dana, a quick note on INV-00377 for the March service visits, now 14 days past due. I’ve attached the invoice and the signed work orders again. Could you let me know when it’s scheduled?

Credits, discounts and short pays get named instead of left as mystery balances. Applying it waits for one yes.

Autopilot for the busywork. Your team stays in charge.

Everything duebird prepares waits for a yes, usually one click for a whole document, and everything it did can be looked up later.

Questions teams ask us

Does the AI calculate the invoice?
No. The AI reads documents and suggests what they mean. Prices come from your price lists, contracts and the customer's PO. Quantities come from the documents. Line totals and tax are calculated by the system the same way every time.
Do our customers have to change anything?
Nothing. They keep sending POs and paperwork the way they do today, and invoices keep arriving from your own address. They'll just notice the invoices are right.
What if duebird gets something wrong?
You see it before anything goes out. Every invoice is approved by a person, every line shows the document it came from, and a value you correct stays corrected.
Can a customer's email trick it into doing something?
Instructions come only from your team and the standing notes you write for each customer. Text inside a customer's email or PDF is read as information, never as a command, and anything it leads to still needs a person's approval.
Can it do more than the person it's working for?
No. It has no direct access to your data. Every change goes through the same permission checks as the person it's working for. If that person can't add a product, neither can duebird.
Will this replace someone on my team?
It replaces the retyping. Your team gets its week back for collections, customer calls and the month-end work that never got done.
Does it handle sales tax?
Yes. Canadian GST, HST, PST and QST and US state sales tax are worked out on every line, with the reason printed beside it.
Which accounting system does it work with?
QuickBooks Online. The connection is encrypted at rest and never shown in full, and posting previews what it will create before it writes anything to your books.
What happens to our documents?
They're kept as received and belong to your company's account. Each company in your account is kept separate, and access is checked on every request.
Can we review your security before we start?
Yes. On the call we'll walk your team through where your data is stored, who can reach it and how access is checked.
What does it cost?
Early customers get pricing agreed with us directly. We'll go through it on the call.
