Automating accounts receivable reminders in Miami in 2026

The verdict in three sentences

For an office supplies distributor in Miami carrying 2,400,000 USD in receivables and a days sales outstanding of 95 days, automating reminders by email, SMS and WhatsApp, connected to the accounting system, costs between 10,000 and 35,000 USD with a local agency in 2026 (market estimate), while Kolonell's simple custom application grid is 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR), delivered in 6 to 8 weeks. Cutting DSO by 15 days frees about 380,000 USD of cash, several times the project cost in the first year. Success depends less on the tool than on a reminder sequence approved by sales leadership and applied without exceptions.

Why manual collections are so expensive

In many small and mid-sized US distributors, collections rely on one AR clerk who calls customers when time allows, usually at month end. The result: net 30 invoices are only chased at day 60, large accounts get special treatment, and nobody remembers which payment promise was made on the phone.

An automated system reads open invoices every night from the accounting system (QuickBooks, NetSuite, Sage Intacct or a CSV export), applies a reminder calendar and logs every response. The AR clerk only handles disputes and key accounts.

What the project includes and what it costs

Recurring costs stay low: for 400 invoices a month and three reminders on average, SMS spend is around 30 to 60 USD per month. Kolonell maintenance, if subscribed, is 35,000, 75,000 or 120,000 FCFA per month (about 50, 110 or 180 EUR) depending on service level.

Florida and US specifics to anticipate

Public entities and school districts pay through their own budget cycles: aggressive automated chasing is counterproductive there, so they go into a separate segment with spaced reminders and a sales alert. SMS to business contacts still requires consent under the TCPA and carrier 10DLC registration, which takes 1 to 3 weeks. Card payment links speed up small invoices under 5,000 USD, but surcharging rules and processing fees (2.5 to 3.5%) must be decided upfront.

Mini case study

Carlos, CFO of an office supplies distributor in Miami, generates about 9,200,000 USD in annual revenue, i.e. 25,200 USD per day. At 95 days DSO, receivables reach 2,400,000 USD. Bringing DSO down to 80 days lowers receivables to about 2,020,000 USD: 380,000 USD of cash freed. His credit line costs 9% per year: he saves about 34,000 USD in interest per year. Add 3 days per month of recovered AR time and fewer write-offs: with a 25,000 USD project, payback is measured in months, not years.

FAQ

How long before DSO improves?

First effects appear after a full billing cycle, 60 to 90 days. A reduction of 10 to 20 days over 6 months is a common 2026 order of magnitude when the sequence is applied without exceptions.

Will customers resent automated reminders?

Tone and frequency are set per segment. A friendly reminder 3 days before the due date is usually well received, and key accounts can be excluded from SMS to receive only personalised emails.

Do we need to change accounting software?

No. The connection uses an API when available, otherwise a daily automated export. Plan 1 to 2 weeks of work for software without an API.

What do SMS and WhatsApp cost per month?

An SMS costs 0.01 to 0.03 USD in the US, a WhatsApp Business conversation 0.03 to 0.08 USD. For 400 invoices a month, the total usually stays under 80 USD.

Can customers pay directly from the reminder?

Yes, each message can include a card or ACH payment link with the invoice reference. Matching then happens automatically in 70 to 90% of cases.
