How InvestingChannel went from 20 days to 2

InvestingChannel sends 100+ advertiser invoices every month. Before maars.io, invoicing took 15 days, and reconciling publishers took another 5. Now advertiser invoicing and publisher earnings reconciliation are completed together in 2 days, from one ledger.

"Invoices go out accurate, the books close faster, and the team spends the time it got back on collections."

20 days → 2 days15 days of invoicing plus 5 of publisher reconciliation, now completed together

The problem

You sit in the middle of the money. Month-end proves it.

Every month you invoice advertisers, match their numbers against what actually delivered, work out each publisher's share, and get payments out on time. Most networks still do it across exports and spreadsheets.

Invoices that don't match delivery

Advertiser IO terms, ad server numbers and third-party counts rarely agree. Every gap you miss is revenue you either never bill or have to credit back later.

Payout math that eats days

Different rev-share terms, floors, fees and adjustments for every publisher. One wrong formula in a spreadsheet and the whole payout run is off.

Publishers asking "why is my check lower?"

Without a clear trail from advertiser invoice to publisher payout, every question becomes an investigation, and every mistake costs you trust.

Before and after maars.io

Without maars.io	With maars.io
Delivery reports from every ad server, SSP and DSP, matched by hand	One reconciliation that pulls them together
Revenue shares kept in spreadsheets, one formula per publisher	Revenue share and CPM fees set once per site and product type
Earnings calculated manually after advertisers are invoiced	Earnings calculated automatically from the same numbers
Advertiser billing and publisher reconciliation as two separate jobs	One connected ledger for both sides
15 days to invoice, then up to 5 more for publishers	Advertiser invoicing and publisher earnings reconciliation completed together in 2 days

One ledger

Both sides of the money. One ledger.

Advertiser invoices and publisher earnings come from the same reconciled numbers, so they always tie out. No second spreadsheet, no second close.

Connected

Every source in one place.

API integrations with ad servers, SSPs, DSPs and other third-party systems. Where there's no API, upload the file. Everything lands in one schema.

Automated

Both sides in the same run.

Each site's revenue share and CPM fees are applied automatically. Advertiser invoices and publisher earnings come out of the same reconciliation.

Traceable

Every dollar has a trail.

Every publisher dollar traces back to the advertiser, invoice and delivery behind it, so "why is my check lower?" takes minutes to answer.

How it works

Three steps to a faster close.

01
Connect.
Add your advertisers, publishers and sites once, with each site's revenue share by product type and CPM fees by datasource. Connect your ad server, SSPs and DSPs by API, or upload files.
02
Reconcile both sides.
maars.io matches delivery against each advertiser's IO and flags every gap before you bill. Publisher earnings are calculated from the same numbers: gross, minus CPM fees, times revenue share.
03
Close in 2 days.
Advertiser invoicing and publisher earnings reconciliation are completed in the same run: send accurate invoices and download the earnings report your team pays publishers from. Then spend the time you got back on collections.

Features

Built for the business in the middle.

Advertiser invoice reconciliation

Match every invoice against ad server and delivery data. Catch under-delivery, over-billing and missing line items before invoices go out.

Revenue shares by site

Set each site's revenue share by product type, and CPM fees by datasource. maars.io applies them to reconciled revenue, not raw reports.

Partner CRM

Every advertiser, agency, publisher, site, vendor and contact in one place, with billing addresses and each site's revenue share terms.

Earnings report

Download any period as a CSV: one row per site, advertiser and invoice, with gross, CPM fees, revenue share and net after fees. You pay publishers your way; maars.io makes sure the amounts are right.

Audit trail

Every publisher's earnings trace back to the advertiser, invoice and delivery behind them. Answer any publisher question in minutes.

Sales pipeline to billing

Track opportunities, insertion orders and campaigns in one place, with booked revenue rolled up by advertiser and rep on the dashboard.

Insertion orders to your ad server

Push a closed deal or insertion order straight from maars.io into your ad server to create the campaign shell. It covers the order-to-ad-server step an OMS handles, without a separate order management system to license and maintain.

Available today: everything above. Coming soon: an in-app publisher earnings view; today the same figures come in the earnings report. maars.io calculates and reports what each publisher is owed. You send the payments.

For every team in the close

Each team sees the part it owns.

Access is set by group, so finance, ad ops, publisher operations and sales each work from the same ledger without stepping on each other.

Finance

Accurate invoices, a faster close and more time for collections.

Ad ops

Delivery against contracted units, with billable units you can adjust before invoices go out.

Publisher operations

Earnings by site and advertiser, and a clear answer to "why is my check lower?"

Sales

Pipeline through IO and campaign to booked revenue, by advertiser and rep.

What counts as a publisher

Each company you pay, however many sites or newsletters it owns. If you pay several entities under one parent company separately, each entity counts.

Moving between tiers

If you go over your plan's limit two months in a row, your plan moves to the next tier from the following month. One busy month doesn't change your bill.

90 days of onboarding

Every plan includes 90 days of hands-on onboarding, including initial setup, connection support and workflow configuration. Additional integrations or custom development are scoped separately. After day 90, your plan's standard support continues.

FAQ

Questions networks ask.

Does maars.io send payments to publishers?

No. maars.io calculates exactly what each publisher is owed and gives you an earnings report to pay from. You send payments through your own bank or payout service, so the money never leaves your control.

Can we keep our existing rev-share contracts?

Yes. Each site gets its own revenue share for each product type, plus CPM fees by datasource, set once in the site settings. Earnings use those terms automatically.

What if our data isn't in an API?

maars.io connects by API to ad servers, SSPs, DSPs and other third-party systems. Where there's no API, upload delivery reports and invoice files directly.

How long does setup take?

About 30 days from kickoff to your first month reconciled. Week 1: kickoff and access to your data. Weeks 2–3: we connect your sources and load your advertisers, publishers, sites and revenue shares. Week 4: a parallel close, checked against your current numbers. You finish with your first month reconciled in maars.io, and hands-on onboarding continues for the full 90 days. Additional integrations or custom development are scoped separately.

Can I try it before a call?

Yes. The live demo and the guided tour run on sample data with no sign-up. Reconcile a month, upload a file, move a deal through the pipeline, see publisher earnings, and reset it whenever you like.

Is our data secure?

Yes. Your data is encrypted in transit and at rest, kept separate from every other client's, and backed up daily. Access inside maars.io is controlled by role, so account managers, finance and publisher operations each see only what their group allows. Our team accesses your data only to support you, and that access is logged. Publisher payments stay in your own bank or payout service, so maars.io never holds the money.
