/ The specific comparison dimensions
Where firms differ.
| Dimension | BQP | Big-4 |

/ Combined engagement model
When both firms work together.
- Common structure for foreign-parent Indian subsidiary: Big-4 as group auditor (US / UK HQ parent) + BQP as Indian specialist (TP + FEMA + ESOP + specific advisory).
- Pre-IPO (Main Board): Big-4 as auditor + BQP as pre-IPO specialist advisor (SEBI ICDR + Ind AS restatement + DRHP input).
- Cross-border M&A: Big-4 as global DD lead + BQP as India specialist DD (tax + FEMA + Rule 9B + 56(2)(viib) legacy).
- BEPS Pillar 2: Big-4 as group Pillar 2 advisor + BQP as India QDMTT + Form 3CEAE/F/G specialist.
- Portfolio PE / VC: Big-4 at specific larger portfolio companies + BQP at smaller mid-market portfolio.
No conflict - complementary. BQP regularly works alongside Big-4 teams on cross-border mandates.

FAQ
Common questions, answered.
Should my startup engage BQP or Big-4?
Depends on stage + budget + ambition. Pre-Series B / mid-market: BQP typically better fit - specialist attention, scoped fee, partner-level, faster. Series C+ / unicorn / pre-IPO Main Board: often Big-4 for brand + global network, BQP for specific specialist areas. Combined engagement common.
Is BQP's fee materially different from Big-4?
Yes - typically 50-70% lower for comparable scope due to lower overhead + partner-direct delivery model. Scoped engagement letter means fixed fee + no hourly surprises. For mid-market mandates, this adds up to significant savings while maintaining ICAI-qualified CA competence.
Does BQP coordinate with Big-4 on cross-border matters?
Yes - standard. BQP's work-product feeds into Big-4 group audit + global tax structuring + Pillar 2 compliance. Co-ordinated with Big-4 teams on specific mandates: Indian subsidiary audit + global group audit; India DD + global DD; India Pillar 2 QDMTT + group Pillar 2 compliance. No conflict - complementary.
What if my Indian subsidiary needs Big-4 brand for lender comfort?
Common. Structure: Big-4 as statutory auditor for lender comfort + BQP as advisor for TP + FEMA + specialist matters. Both firms co-ordinate on information flows. BQP's work-product goes into Big-4 statutory audit workpapers.
For urgent matters (Form 15CB, Section 148 response), BQP is better?
Typically yes. BQP's 24-48 hour urgent response time is faster than most Big-4 standard engagement cycles. For time-sensitive specialist matters (Form 15CB CA certificate for VC funding wire, Section 148A show-cause response, FEMA deadline), BQP's partner-direct model + specialist depth works better.
