Sprout Invoices uses four custom post types (sa-invoice, sa-estimate, sa-client, sa-payment) with totals, line items, balances, and per-payment records all in postmeta. Sprout is one of the few WordPress invoicing plugins that handles partial payments as a first-class concept, which makes the dataset unusually rich for reporting.

SleekView Charts builds a dashboard that takes advantage of that. A KPI card sums outstanding balance across all invoices. An Area card plots daily issuance for both invoices and estimates. A Pie card splits the ledger by status (paid, partial, unpaid, overdue, pending). A Bar card ranks clients by lifetime invoice total.

The partial-payment slice on the status donut is the cue Sprout's default admin never surfaced as a chart: half-paid invoices stop hiding inside the unpaid filter. Drill-through into rows preserves Sprout's si_invoice_paid hooks on inline edits.

Sprout Invoices is one of the few WordPress invoicing plugins that treats partial payments as a first-class concept, which matches how service businesses actually bill. Half upfront, half on delivery; deposit on signing, balance net 30; staged payments through a long project. The data is all there in sa-invoice, sa-payment, and the computed balance, but the default admin treats invoices as binary (paid or unpaid) and the partial-payment dimension stays invisible.

A four-card chart dashboard exposes it cleanly. Outstanding balance summed across unpaid, partial, and overdue gives finance the single cash-flow number that matters. Daily issuance stacked by doc type plots sales activity.

Status mix with a real partial slice turns half-paid invoices into a visible cohort. Per-client revenue ranking gives agencies the portfolio view they have always assembled in spreadsheets. Drill-through preserves Sprout's hooks, so recording payments and pushing statuses from a chart drill-down behaves identically to the default editor.

The plugin already had the right data model; the dashboard layer finally makes it observable.
