GT Extensions for FluentCart 2.9.0

Recurring invoices. Open an issued invoice and choose Repeat this invoice to bill the customer every 1 to 12 weeks, months or years, starting on a date you pick and ending never, after a number of invoices, or on a date. Each period creates a new invoice with its own number and payment link, then emails it or saves it as a draft for you to review. Invoices → Recurring lists every schedule; pause, resume or stop them there. A schedule on the 31st uses the last day of shorter months, and a site that missed its scheduled tasks creates one invoice and logs the skipped periods.
Deposits. Ask for a percentage or fixed amount first on digital and service invoices and quote proposals. When the deposit is paid, a balance invoice for the rest is issued and emailed automatically. Deposit and balance add up to the full total and tax exactly.
Reminders timed from the due date. Email settings takes up to four reminders before, on, or after the due date, with a new overdue message for those after it. Turn reminders off for a single invoice in its editor. Issued invoices list the reminders still queued. Quote proposals can send one reminder before they expire.
Fixed: with automatic reminders on, only one unpaid invoice at a time received its reminder, and back-in-stock emails for several products could queue only the first product. Action Scheduler's unique flag ignores the job's arguments, so jobs are now unique per invoice and per product option.
New /store agent skill and gtfc_agent() commands: store.summary, order.list, order.get, stock_alert.list, stock_alert.send, product.details.get, product.details.set, page_access.pages, page_access.add and page_access.remove, plus invoice.schedule, invoice.unschedule and invoice.schedules. Changes support dry_run first. The bundled script runs any command with gtfc.py call.
The {due_date} email placeholder now uses your site's date format.
Dark mode fixes for FluentCart's dark theme. The Product details card on the product editor now has dark text boxes, checkboxes, dividers and a readable Add a detail link and Save button instead of white boxes on a dark card.
The Invoices and Quotes screens, the Checkout Builder layout picker and the Conditional module badge follow dark mode too, including the product search results, status pill, activity log and invoice layout picker.
The checkout details table in FluentCart's order view no longer shows dark grey labels on a dark background. It takes the page's text colour, so it reads well in light mode, dark mode and emails.

Requires FluentCart. Invoices and the other store modules require FluentCart 1.6.4 or later. The agent skills need the free Site Agent plugin (https://gauravtiwari.org/product/site-agent/); Site Agent 0.4 or later serves them to connected agents without an extra install.
