28-DAY BILLING
13 Cycles a Year.
Native From Day One.
The industry-standard billing cadence 13 cycles per year, mapping cleanly to four weekly service visits. Built into PortaPro from the ground up, not bolted on with workarounds.
REVENUE IMPACT
An extra cycle is real money.
13 cycles per year at the same per-period rate produces ~8.3% more annual revenue than monthly billing. Same customer, same rate, more cycles.
ANATOMY OF A YEAR
13 cycles, not 12.
EXACT MATH
Pair 28-day cycles with 28-day rates.
Mixed rate periods normalize automatically — a monthly rate on some sites, a per-28-day rate on others — to keep the charge accurate for the customer's actual billing window. The MRR display rolls everything up to a comparable monthly equivalent.
WHY IT HOLDS UP
Aligned to the work, and to the standard.
Aligned to the work
Weekly service routes naturally produce one billing cycle every four weeks. Customers receive an invoice for the work they just had done — not for the calendar month that just ended.
The standard at scale
ServiceCore supports 28-day billing because it's the standard at scale. PortaPro supports it because we built for the way the industry actually works.
