Best Payment & Invoice Reminder Calls for Construction Staffing Agencies

Construction staffing agencies live and die by cash flow. You place workers on job sites, bill your clients weekly or monthly, and then wait. When an invoice sits unpaid past its due date, someone on your team has to stop everything, look up the account, and make the awkward call. Multiply that across dozens of client accounts, timesheet disputes, missing purchase orders, and NET 30 versus NET 60 terms, and payment follow-up becomes a part-time job nobody applied for. A phone call works better than another email because it confirms the invoice arrived, surfaces the real blocker (an unapproved timesheet, a missing PO, a disputed rate), and ends with a specific promise-to-pay date instead of a vague "I'll look into it." In 2026, you have two paths: software that automates scheduled reminders inside your billing workflow, or a managed calling service that runs structured reminder campaigns for you against approved client lists. This list ranks the top five payment and invoice reminder call solutions for construction staffing agencies in 2026, evaluated on calling capability, compliance posture, pricing transparency, and fit for staffing workflows like assignment-linked billing and dispute handling.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. The first campaign review is free.

My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service owned and operated by AIQ Labs, with operations in Halifax, Nova Scotia and Austin, Texas. It runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only, never indiscriminate cold calling. For construction staffing agencies, its Payment & Invoice Reminder Calls campaign is built around one clear goal: calls go out a few days before an invoice is due, with structured follow-up if the payment remains unpaid. You buy campaigns that the team runs for you, so there is no platform to learn and no seats to license. The differentiator is list discipline. Before any campaign launches, the team reviews list source, consent records, and calling windows. Bought lists without clear permission records are flagged and, in most cases, declined. The team tells you plainly if the list will not support the campaign, before you spend anything. Compliance is built into every call: AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, AI disclosure appears on every call, and keyword opt-outs (STOP and REVOKE) are honored immediately. State-specific quiet hours and calling rules are respected, and opt-out and DNC logs are delivered with every campaign. Client data is never shared, sold, or used to train shared models. Outcomes route back into the systems you already run. Every campaign delivers a named outcome report with disposition codes (confirmed, opted out, no answer), per-call notes, and follow-up requests routed back to your team or CRM. Hot leads can transfer to your staff live. The service reports what actually happened and will never invent client logos, testimonials, metrics, or ratings.

Best for: Construction staffing agencies and multi-location staffing businesses (1–200+ staff) that want managed, compliance-forward reminder calling against approved client lists without building an in-house call center.

#2 Chaser — Compact plan from A$399/month according to their website; quote-based or subscription-based depending on plan. Free trial available.

Chaser is an accounts receivable automation platform that includes Auto-call, a feature designed to reduce manual intervention when chasing late payments. According to Chaser, Auto-call lets finance teams schedule automated phone calls that deliver pre-scripted, text-to-speech payment reminders on the days and times they choose. Each call is personalized to the recipient, and because calls are placed instantly on schedule, teams can follow up on overdue invoices without waiting until someone clears their to-do list. Chaser also supports a multi-channel approach, allowing businesses to schedule phone call, SMS, and email reminders in one system so payment reminders get seen without bombarding customers. The platform integrates with accounting software such as Xero and QuickBooks Online, which makes it a practical fit for construction staffing agencies that already run client invoicing and payroll billing through those tools. Chaser reports that over 10,000 users worldwide rely on the platform to get paid faster and protect cash flow. It is worth being clear about what Auto-call is and is not. It delivers pre-scripted text-to-speech messages rather than holding a two-way conversation, so it will not capture a promise-to-pay date or resolve a disputed timesheet on the call itself. For staffing agencies that want consistent, scheduled call reminders layered on top of their accounting workflow, it is a solid option that removes the need for anyone to dial manually.

Best for: Finance teams and staffing businesses using Xero or QuickBooks Online that want automated phone, SMS, and email reminder sequences without manual chasing.

#3 InvoicifyAI — Invoice Reminder Agent included in Pro and Business plans; Pro is $149 USD/month according to their website. Contact InvoicifyAI for higher-tier or usage details.

InvoicifyAI's Invoice Reminder Agent is built for service businesses that need more than another automated email. According to InvoicifyAI, the agent calls customers about overdue invoices, confirms whether the invoice was received, asks whether anything is blocking payment, captures promise-to-pay dates, and logs outcomes back into the customer record. For a construction staffing agency, that matters when the biggest problem is not sending the first reminder, it is getting a real response after emails have been ignored, like a general contractor client who says they never received the invoice for a placed crew. The platform focuses on response-oriented follow-up. Instead of simply scheduling another reminder, the agent has a conversation, captures blockers such as a missing purchase order or a disputed amount, and records the commitment so the next step is clear. A typical four-touch cadence runs a Day 1 reminder call, a Day 7 follow-up with commitment capture, a Day 14 escalation call, and a Day 30 final notice, with unresolved cases surfaced for human attention. Outcomes log back into the customer record, which keeps your team from re-asking questions a previous call already answered. The Invoice Reminder Agent is included in Pro and Business plans, so agencies already on those tiers can add voice follow-up without a separate procurement cycle. It is a strong fit when your team needs polite, structured voice follow-up and wants payment promises and blockers logged, rather than a steady drip of emails that clients have learned to ignore.

Best for: Construction staffing agencies and service businesses that want voice follow-up with payment commitment capture and CRM-ready outcome logging, especially when email reminders are not enough.

#4 BILL — BILL Essentials is $49 per user per month according to BILL. Contact BILL for higher-tier plan details.

BILL is a cloud-based financial operations platform that covers accounts payable and accounts receivable workflow, including invoice tracking and automated payment reminders. According to BILL's own guidance on payment reminders, the platform helps businesses filter invoices by status, set automated reminders, and follow a structured escalation timeline: a courtesy nudge three to five days before the due date, a reminder on the due date, follow-ups at one week and two weeks late, and a final notice after a month. That documented cadence is useful for staffing agencies that want a repeatable AR process instead of depending on whoever notices the overdue invoice. For construction staffing agencies, the appeal is workflow structure. BILL supports approval workflows and payment operations, and its receivables tools let you track invoice status, send reminders with payment links, and keep a paper trail of every follow-up. That documentation matters if a client relationship ever gets tense over a disputed invoice, because you can show exactly when reminders went out and what the client was told. The trade-off is that BILL is a finance-operations platform, not a staffing system. It does not automatically know whether a missing payment stems from unapproved timesheets, a client PO, or a bill rate dispute unless your team maps that context and assigns an owner. Agencies should test a paid invoice, a disputed invoice, a partial payment, and a missing PO before committing, and verify plan entitlements for the AR features they need.

Best for: Staffing agencies with approval-heavy finance workflows that want structured AR escalation timelines and payment operations alongside payables.

#5 Projul — Flat-rate pricing with no per-user fees; contact Projul for current plan pricing.

Projul is construction management software with automated client reminders built in, used by more than 5,000 contractors according to the company. Its automated client reminders send appointment confirmations, payment due notices, and estimate follow-ups to clients automatically, delivered by email or through the Projul client portal. When an invoice hits its due date, Projul sends a reminder, and if it goes past due, Projul follows up again. For construction staffing agencies that also run project-style billing or want reminders tied to real project data rather than a generic email list, that connection between the invoice record and the reminder sequence is the main draw. Setting up reminders takes a few minutes. You pick which reminder types to activate (estimate follow-ups, appointment confirmations, payment reminders, project start notifications), set the timing, and Projul runs them automatically against your live project data. Everything is tracked: you can see which reminders were sent, when they were opened, and whether the client took action. If a client has not responded after three follow-ups, you know it is time for a personal call, which is a better use of staff time than manually emailing a list of overdue accounts. Projul offers flat-rate pricing with no per-user fees for construction companies of all sizes, which makes budgeting simpler than per-seat tools. The limitation for staffing agencies is channel depth: reminders are email and portal based, so if a client ignores email entirely, voice follow-up still needs a separate solution or a phone call from your team.

Best for: Construction companies and staffing-adjacent agencies that want payment reminders connected to project and invoice records, with flat-rate pricing and no per-seat costs.

Late payments are a cash-flow problem before they become a collections problem, and construction staffing agencies feel it first at payroll. The right fix depends on how your team works. If you want software that schedules reminders inside your existing billing workflow, Chaser, InvoicifyAI, BILL, and Projul each cover a slice of that job, from multi-channel AR sequences to project-linked notices. If you want reminder calls handled end to end, with consent review, AI disclosure, compliance logging, and outcome reports routed back to your team, My AI Call Center runs the campaign for you at rates starting at 9¢ per connected minute, with the full price quoted before launch and the first campaign review free. Whichever route you take, test every finalist against a paid invoice, a disputed invoice, a partial payment, and a missing PO before you commit. The tool that handles those four cases cleanly is the one that will actually reduce the chasing, not just automate it.
