Marketing agencies carry more of their clients' money than most service businesses: media spend fronted on the agency's card, production costs paid to freelancers, and retainer months already worked. Collections software for marketing agencies follows up on every one of those invoices so account managers can keep the client conversation about the work.
Abivo is collections software for marketing agencies: its AI agent, Kate, follows up on overdue retainer, project, media and production invoices by phone, text message and email, straight from your accounting system, and hands any dispute or sensitive account to the account lead who owns the relationship.
Best for: digital, creative, advertising, performance, PR and branding agencies, and web and content studios that bill businesses on net terms, and that have more open invoices than the finance lead or the founders can follow up on each week.
Is This Also Accounts Receivable Software for Digital, Creative and Advertising Agencies?
Yes, for the part of accounts receivable that gets invoices paid. Your agency management and accounting systems handle time, estimates, billing and payments. Abivo connects to the accounting system and handles the follow-up on every overdue invoice by phone, text and email. That is the step most agencies leave to an account manager who does not want to raise it. It works the same way for digital agencies, creative agencies, advertising agencies, media buying agencies and PR firms.
Why Is A/R So Hard for Marketing Agencies?
Account managers do not want to be the bill collector. The account lead spends the week building trust with the client's marketing team. Asking that same person for money feels like it puts the relationship at risk, so the question waits until the invoice is badly overdue.
The agency often pays first. Paid media, stock licensing, printing and freelance production are frequently paid by the agency and rebilled. When the client is slow, the agency is financing its client's campaign.
The person who approves the work is not the person who pays. A marketing director signs off on the campaign. Payables pays the invoice, often only after a PO, a vendor setup form or a portal upload that nobody on the agency side knew about.
Retainers quietly stack up. A monthly retainer from a busy client is easy to let slide one month. By the time anyone notices, three months are open and the conversation is harder.
Results become a reason to hold payment. When a campaign underperforms or a client is unhappy with a deliverable, the open invoice becomes leverage, even when the work was delivered as agreed.
What Should Collections Software Do for a Marketing Agency?
Judge any tool against this list:
Work every overdue invoice, including retainers. Monthly retainers are where the count lives and where slippage starts.
Reach payables, not just the marketing contact. Follow-up should go to the person who releases payment and ask for the PO number when one is needed.
Use phone, text and email. A client's payables team that ignores email will often answer a short call or a text with a payment link.
Keep account managers out of routine chasing. The person presenting the next campaign should not be the one asking about the last invoice.
Hand anything sensitive to the account lead. Scope questions, performance complaints and key clients go to a person with the full history.
Sync with your accounting system and log everything, so account leads can see every call and promise to pay before their next client meeting.
Which Invoices Should the Software Chase First?
Chase by invoice type, because each type stalls for a different reason.
Invoice type | Typical size | Why it stalls | What good follow-up does |
|---|---|---|---|
Monthly retainer | Mid, recurring | Client let one month slide, approver changed, missing PO | Follows up every month on the same cadence and asks for the PO on the first reminder |
Project fee (campaign, website, rebrand) | Large | Client waiting on final sign-off, milestone disputed | Confirms the invoice was received, asks for a payment date, routes sign-off questions to the account lead |
Media spend rebill | Large | Client treats it like a normal invoice while the agency has already paid the platform | Follows up early and steadily, so the agency is not carrying spend for long |
Production and freelance pass-through | Small to mid | Low priority for the client's payables team | Follows up with the fee invoices so they do not age on their own |
Out of scope or change request | Small to mid | Client questions whether it was covered by the retainer | Logs the question and hands it to the account lead |
Final invoice after a client leaves | Mixed | Client has moved to another agency or brought the work in house | Confirms what is still open and routes any disagreement to the founder or account lead |
The retainer rows hold the count. The media and project rows hold the cash the agency has already spent. Good software covers both.
How Does Autonomous Follow-Up Work on Agency Invoices?
An autonomous agent does the follow-up itself. Kate calls the client's payables contact, says she is calling on behalf of your agency, confirms the invoice and what it covers, answers routine questions such as "can you resend that" or "which month is this retainer for", asks for a PO number if one is needed, and agrees on a payment date within the rules you set. We walk through a full call in how an AI agent calls customers about overdue invoices.
A typical cadence on an overdue retainer invoice:
Day 1 overdue: a friendly email with the invoice and a payment link.
Day 7: a text message to the billing contact.
Day 14: a polite phone call to confirm receipt, ask for any missing PO and get a payment date.
Day 21 onward: calls and emails on a steady rhythm, each one logged in the account history.
At any point: a scope question, a complaint about the work or a request to speak with someone goes straight to the account lead.
How Do You Handle Scope Disputes, Performance Complaints and Paused Campaigns?
Three replies cause most of the friction on agency invoices.
"That was supposed to be in the retainer." Scope questions are relationship conversations. Software should record the objection, pause follow-up on that invoice and hand it to the account lead who agreed to the work, with the history attached.
"The campaign did not perform." A complaint about results is not something software should argue. Kate logs it and routes it to the account lead or founder straight away. How to respond, whether with a make good, a credit or a conversation, is a decision for your agency.
"We paused everything." When a client pauses a campaign or ends the relationship, the invoices for work already delivered still need attention. Good follow-up stays polite, confirms what is open and hands the account to a person the moment the client wants to discuss it. Whether to pause work for a client with open invoices is a decision for your agency, never for software.
What About Teams With Three or More People in Collections, and When Account Managers Own Client Relationships?
Larger agencies and holding company units often have a finance team with billing and collections roles. They make calls, but they focus on the biggest balances, and retainers and pass-through invoices from smaller clients wait. Meanwhile, many account leads would rather finance did not call their clients at all.
An AI agent changes the split. Kate covers every overdue invoice on a set cadence, and your finance team handles the accounts that need judgment. For clients an account lead wants to keep close, Kate takes the routine reminder and hands anything sensitive straight to the account lead. The account manager stays the strategic partner, and the follow-up still happens.
What About QuickBooks, Xero and the Rest of Your Stack?
Many agencies track time, estimates and jobs in an agency management or project tool that posts invoices to an accounting system. Abivo connects to the accounting system: Kate reads open invoices and aging, follows up, and logs every conversation and promise to pay, so your books stay the source of truth. Integrations include QuickBooks, Xero, NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central and Chargebee, and a CSV upload covers anything else, including exports from your agency management tool. Details are on the product page.
What Results Should a Marketing Agency Expect?
Results depend on how old your overdue invoices are, how many clients have a working payables contact on file, and how much media and production you rebill.
The closest proof is in service companies. OFS Group, a fire safety and appliance repair service company, put its overdue ledger in front of Kate and collected $842,518 in four months, with DSO down by more than 30 days. OFS is not an agency, but it had the same core problem: more open invoices to business clients than the office could follow up on. We would still rather play you real call recordings than promise a number for your ledger.
What Should You Measure After Switching?
Share of invoices over 60 days, by invoice type. Retainers and pass-throughs should fall first.
Media rebill exposure. How much spend the agency has paid and not yet collected.
Contact coverage. How many clients have a payables contact on file, separate from the marketing team.
Escalations by reason. Scope, performance, missing POs and departed clients, each counted.
Promises kept: clients who paid by the date they gave.
Practical Takeaways for Marketing Agencies
Take routine follow-up off account managers. They should hear about an account only when it needs them.
Treat media rebills as the agency's own cash, and follow up on them first.
Get the PO and the payables contact before the first invoice goes out.
Keep scope and performance conversations with the people who own the client.
Ask any vendor to let you hear real calls.

Frequently Asked Questions
What is the best collections software for marketing agencies?
Look for software that follows up on every overdue invoice by phone, text and email, covers retainers, projects, media rebills and pass-throughs, reaches payables and asks for PO numbers, hands scope and performance questions to the account lead, and syncs with your accounting system. Abivo does this with an AI agent, Kate, that follows up on its own and hands sensitive accounts to your team.
How can a marketing agency get paid faster?
Bill retainers in advance, invoice media and production as soon as they are committed, set up the PO and payables contact at onboarding, include a payment link, and follow up on every overdue invoice every week. Abivo automates that follow-up so account managers do not have to.
Is collections software the same as accounts receivable software?
Collections software is the part of accounts receivable software that gets overdue invoices paid. Abivo focuses on that part and connects to the accounting system that handles the rest.
Does it work for digital, creative and advertising agencies?
Yes. Abivo works from the accounting system where your invoices land, or from a CSV export, and follows up on every overdue retainer, project and rebill invoice, whatever kind of agency you run.
Will an AI agent hurt our client relationships?
Kate is polite, says she is calling on behalf of your agency and sticks to the invoice. Any client who pushes back, and any account a lead wants to handle personally, goes to a person.
How quickly can an agency start?
Connect your accounting system or upload a CSV, start with a defined set of overdue invoices, and expand from there.
