Anken Timer & Invoices

Anken Timer connects project time tracking, monthly contract settlement, and invoice issuance for freelancers and independent workers. No account is required. TRACK SOURCE WORK - Start and stop project timers with one tap. - Starting another project closes the running timer. - Add missed work manually. - Records crossing midnight are split by day. RESOLVE MONTHLY CONTRACT SETTLEMENTS - Version each project's base monthly fee, lower and upper hour band, excess and deduction rates, rounding rule, and effective period. - Aggregate the selected month's source segments in exact seconds. - Deterministically classify the result as in-band, excess, or shortfall. - Inspect the ordered source, rounding, band, and amount calculation trace. - Apply an explicit minute correction only with a reason, without rewriting source records. - Block invoice issue until every monthly-settlement line is reviewed. - Preserve the terms snapshot, source segments, correction, trace, and review time in the invoice and A4 PDF. INVOICES AND REPORTS - Support hourly, fixed-fee, and monthly-settlement projects. - Review consumption tax, withholding, registration number, and totals. - Generate a numbered Japanese-style A4 PDF. - See monthly project hours, estimated amounts, and daily activity. Settlement, tax, withholding, and rounding are calculation aids based on your input. They are not contract interpretation or legal, tax, or accounting advice. Check the agreement and work records before issue. FREE WITH ADS Business features remain available without purchase. Ads are a banner and interstitials limited to natural pauses after stopping a timer, issuing an invoice, or generating a PDF. One non-consumable Remove Ads purchase hides both formats.
