Mercer's success was gained despite the failures of a great many persons to pay the fees they owed him. In 1745 he listed 303 "Insolvents, bad & doubtful debts." That matters were no worse may be attributed to a high average of responsible clients. Among them were such well-known Virginians as Daniel Dulaney, William and Henry Fitzhugh, William Randolph, Augustine, John, and Lawrence Washington, Gerard Fowke, Richard Taliaferro, John and Daniel Parke Custis, Andrew and Thomas Monroe, George Tayloe, George Lee, George Wythe, and William Ramsay.

By the early 1740's Mercer was in a position to surround himself with symbols of wealth and prestige. Clothes, a traditional measure of affluence, were now a growing concern for himself and his family. Between 1741 and 1744, the ledger reveals, he purchased from William Hunter a greatcoat, women's stockings, women's calf shoes, morocco pumps, a "fine hat," three felt hats, two dozen "plaid hose," two pairs of men's shoes, one pair of "Women's Spanish Shoes," and "2 p^r Calf D^o." In 1744 and 1745 he bought from Charles Dick two pairs of "women's coll'^d lamb gloves," two pairs of silk stockings, "1 velvet laced hood," a "laced hat," a "Castor" (i.e., beaver) hat, "fine thread stockings," silk handkerchiefs, a "flower'd pettycoat," worsted stockings, and buckskin gloves. From Hugh MacLane, a Stafford tailor, he obtained a suit in 1745.
The rise in Mercer's wealth and prestige is reflected in his patronizing Williamsburg tailors, beginning in 1745 when he settled with George Charleston for a tailor's bill of £6 10s. In 1748 he paid Charleston four shillings for "Collar lining a Velvet Waistcoat." In 1749 he purchased a "full trimm'd velvet Suit" from Charles Jones, the work and materials totaling £7 7s. 4-1/4d., while in 1750 he spent £11 2s. 1-1/2d. on unitemized purchases from the same tailor. In that year he bought also from Robert Crichton, a Williamsburg merchant, "a flower'd Velvet Waistcoat, £5." As the decade advanced, Mercer played with increasing consciousness the role of wealthy gentleman, as his choice of tailors shows.
